Splash is a 1984 American romantic fantasy comedy film directed by Ron Howard, from a screenplay by Lowell Ganz, Babaloo Mandel, and Bruce Jay Friedman, and a story by Friedman and producer Brian Grazer. The film stars Tom Hanks, Daryl Hannah, John Candy, and Eugene Levy. Its plot involves a young man who falls in love with a mysterious woman who is secretly a mermaid. The film was nominated for an Academy Award for Best Original Screenplay.
 It is notable for being the first film released by Touchstone Pictures, a film label created by Walt Disney Studios that same year in an effort to release films targeted at adult audiences, with mature content not appropriate for the studio's flagship Walt Disney Pictures banner. Splash received a PG-rating for some profanity and brief nudity, and was critically and commercially successful, earning over $69 million on an $11 million budget, and received praise for the acting, humor, and chemistry between Hanks and Hannah.
 In 1964, eight-year-old Allen Bauer and his family are taking a boat tour at Cape Cod, Massachusetts. Allen is fascinated by something below the surface and jumps overboard. In the ocean, he encounters a young girl and inexplicably finds himself able to breathe underwater. However, Allen is rescued and pulled back to the surface, and the two are separated. Since no one else saw the girl, Allen comes to believe the encounter was a hallucination.
 Twenty years later, Allen is now co-owner of a wholesale fruit and vegetable business in New York City with his womanizing older brother Freddie. Throughout the years, Allen's relationships have failed as he subconsciously seeks the connection he feels other couples enjoy. Depressed after his latest breakup, Allen returns to Cape Cod, where he encounters eccentric scientist Walter Kornbluth on a diving expedition. When his motorboat restarts, Allen falls into the sea and is knocked unconscious; his wallet drops onto the coral below. Allen later wakes up on a beach, in the presence of a beautiful young woman who is unable to talk. After kissing him, the woman dives into the sea, where she transforms into a mermaid. While swimming underwater, she is sighted by Kornbluth.
 The mermaid finds Allen's wallet, and uses a sunken ship's charts to locate New York. She comes ashore naked at the Statue of Liberty and is arrested for indecent exposure. Using information from Allen's wallet, the police contact him and she is released into his care. The mermaid learns how to speak English from watching television, and is eager to explore the city. Unable to say her real name in human language, she selects "Madison" from a Madison Avenue sign. Madison tells Allen that she will be in New York for "six fun-filled days until the moon is full", unable to return home if she stays any longer. Despite Madison's occasionally outlandish behavior, she and Allen fall in love. Allen proposes to Madison, but she declines and runs away. After some contemplation, Madison returns to Allen and agrees to marry him, with the added promise of telling him the truth about herself after an upcoming dignitary dinner to welcome the President.
 Meanwhile, Kornbluth, realizing that Madison is the mermaid he encountered, pursues the couple, trying to expose Madison by splashing her with water. His first attempts are unsuccessful, and Kornbluth ends up with multiple injuries. Finally, he infiltrates the dignitary dinner, splashing Madison with a hose and successfully unmasking her identity. Madison is seized by government agents and taken to a secret lab, headed by Kornbluth's cold-hearted rival Dr. Ross for examination. As Madison withers away in captivity, Kornbluth learns that the scientists are planning to dissect her, causing him to regret his actions.
 Allen is shocked by Madison's secret and rejects her, but when he voices his disillusionment to his brother, Freddie lashes out at him, reminding Allen how happy he was with her. Realizing that he still loves Madison, Allen confronts the guilt-ridden Kornbluth, who having been rejected by his colleagues, agrees to help rescue her.
 Impersonating Swedish scientists, Allen, Freddie, and Kornbluth enter the lab and smuggle Madison outside. Freddie decides to be arrested in Allen's place, while Kornbluth unsuccessfully tries to stop military troops from catching the couple. Despite being pursued, Allen and Madison make it to New York Harbor. Madison tells Allen that he can survive underwater as long as he is with her, prompting Allen to realize that she was the girl he had met underwater as a child. Madison warns him that if he comes to live in the sea, he cannot return to land.
 Madison dives into the water as the troops close in on them. When they attempt to arrest Allen, he jumps in after her, but starts to drown. Madison kisses Allen, gifting him the ability to swim and breathe underwater. Frogmen try to recapture Madison and Allen, but the couple fight them off and escape. Allen discards his jacket, forsaking his miserable life on the surface and the couple happily swims toward what appears to be an underwater kingdom.
 Screenwriters Lowell Ganz and Babaloo Mandel both make cameo appearances in the film. Ganz plays Stan, the tour guide, in the scene set at the Statue of Liberty. Mandel plays the man in charge of ice skate rentals who tackles Hanks' character when he tries to run out with his skates still on. Director Ron Howard's father, actor Rance Howard, can be seen early in the film as Mr. McCullough, an unhappy customer screaming at Allen about his cherries. Howard's brother Clint Howard appears as a wedding guest, identified by Candy's character as the bride's brother and yelled at by Hanks.
 The film was initially set up at United Artists, but Grazer decided to take the film elsewhere and took it to The Ladd Company, but Alan Ladd Jr. eventually passed on it. According to the documentary on the Splash: 20th Anniversary Edition DVD in 2004, producer Brian Grazer had pitched the film to numerous studios but was turned down repeatedly until Walt Disney Productions, then headed by Ron W. Miller, agreed to produce the film. The key to the proposal's success was that Grazer changed the premise description from the idea of a mermaid adjusting to life in New York City to that about a love story about an ordinary man in New York City meeting a mermaid. An issue at the time of production was the competition between Splash and another announced (but untitled) mermaid film from Warner Bros. that had lined up Warren Beatty as its star. Director Ron Howard promised the studio that Splash would be filmed more quickly and cheaply than the other film, which eventually fell through. Howard turned down directing Footloose and Mr. Mom to direct Splash.
 Several established actors such as Chevy Chase, Dudley Moore, Bill Murray, and John Travolta were considered for the lead role before the producers decided on the then lesser-known Tom Hanks. Hanks was cast as Ganz and Mandel believed that he would great as a "every man" character. According to Howard, the studio would not give him a green light. Murray turned down the part as he wanted to move away from comedies and do serious films instead. Steve Guttenberg also auditioned for the role. Michael Keaton was offered a role, but he declined so he could star in Mr. Mom instead. Before Daryl Hannah was cast as Madison, the role had been previously turned down by P.J. Soles, Tatum O'Neal, Michelle Pfeiffer, Julia Louis-Dreyfus, Melanie Griffith, Diane Lane, Kathleen Turner, and Sharon Stone. Lane chose to do Streets of Fire and The Cotton Club instead.
 Principal photography, which ran from March 1 to June 30, 1983, took place in Los Angeles, New York City, and Gordon Cay, an isle in the Bahamas since purchased by Disney and renamed Castaway Cay. Donald Peterman served as the film's cinematographer, with Jon Fauer serving as camera operator for the film's New York scenes.
 Hannah's mermaid tail was designed and created by Academy Award-winning visual effects artist Robert Short. The tail was fully functional. Hannah swam with the mermaid tail so fast that her safety team could not keep pace with her. According to the DVD documentary, Hannah had been swimming "mermaid" style with her legs bound together since she was a child, due to her fascination with Hans Christian Andersen's "The Little Mermaid" story. However, the exceptionally detailed film tail was difficult to remove. For the sake of efficiency, Hannah at first kept it on while the cast had lunch. In the documentary included on the 20th-anniversary Splash DVD, Hanks recalled how the other cast members would drop French fries over the side of the tank to her as though she were a trained sea mammal, because she could not leave the water while her legs were "shrink-wrapped".
 Produced on a $11 million budget, Splash grossed $6.2 million in its opening weekend and finished its run with a gross of $69.8 million in the United States and Canada, making it the tenth highest-grossing film of 1984. The film also well received by critics and is considered to be one of the best films of 1984. On the review aggregator website Rotten Tomatoes, the film holds an approval rating of 91% based on 44 reviews, with an average rating of 6.9/10. The website's critics consensus reads, "A perfectly light, warmly funny romantic comedy that's kept afloat by Ron Howard's unobtrusive direction and charming performances from Tom Hanks and Daryl Hannah." Metacritic, which uses a weighted average, assigned the film a score of 71 out of 100, based on 15 critics, indicating "generally favorable reviews".
 A negative review came from Roger Ebert of The Chicago Sun-Times, who gave the film 1.5 stars out of 4 and thought the film's biggest failing was casting then-unknown Hanks as the lead rather than the established comedy actor John Candy: "They should have made Candy the lover, and Hanks the brother. Then we'd be on the side of this big lunk who suddenly has a mermaid drop into his life." Colin Greenland of Imagine magazine stated that "Splash is an adult film that has the grace to treat fantasy with sensitivity and a sense of humour."

 A soundtrack album of Lee Holdridge's music for the film was released on both vinyl LP and cassette in the United Kingdom by Cherry Lane Records Ltd in 1984, with the music re-recorded by the Royal Philharmonic Orchestra conducted by the composer and the love theme song covered by Kira McClelland. Both have been out of print for many years. The catalogue numbers for these releases were PIPLP 710 and ZCPIP 710 respectively. In 2000, the original music was released on a 26-track CD in the United States by Super Tracks Music Group. The back cover states that this product is "For Promotional Use Only" and that it has been "Manufactured for the composer...". Although this release is very hard to find brand new and may in fact be out of print, it is still obtainable from certain film soundtrack specialist retailers and also occasionally used from certain online stores. This CD has every track that the LP and cassette have but has a considerably longer running length due to the 12 extra tracks. These extra tracks include more of the original music from the film, the theme song (by Lee Holdridge and Will Jennings) sung by Rita Coolidge and alternate versions of some of the tracks which appear on the LP and Cassette. The catalogue number for this release is LH CD – 02.
 Steven Levitt and Stephen Dubner's book Freakonomics (2006) credits the film with popularizing the name Madison for girls, as does Steven Pinker's The Stuff of Thought (2007). In the film, Hannah's character takes her name from Madison Avenue (itself named after President James Madison) after walking past a road sign. Hanks' character comments that it is not a real name as, at the time, it was a rather unusual name for a woman. However, in the years since the film was released in theaters and re-released on VHS and then DVD, the name's popularity has skyrocketed.
 According to the Social Security Administration, the name Madison was the 216th most popular name in the United States for girls in 1990, the 29th most popular name for girls in 1995, and the third most popular name for girls in 2000. In 2005, the name cracked the top 50 most popular girls' names in the United Kingdom, and articles in British newspapers credit the film for the popularization. In a 2014 interview, Hannah commented on the irony of the name's popularity and subsequent acceptance as a standard first name given its origins as a joke based on Madison being primarily known as a street name at the time:
 It's funny because no one understands the irony, because the whole point of me choosing that name was because it [was such a] silly name...Obviously everyone knew it as the name of the street. No one really saw it as a first name and that was a joke. And now, of course it's not funny at all. It's just like, 'Oh, what a beautiful name!'...It was funny at the time and now it's not even ironic.
 In June 2016, producer Brian Grazer announced that he was working on a remake of Splash, although this version would be told from the point of view of the mermaid, which was more in line with the earlier drafts of the original film. Jillian Bell and Channing Tatum were set to star as a female human and a merman, respectively. Tatum was also set to produce the remake through his production company, Free Association, along with Reid Carolin and Peter Kieran, while Howard and Grazer will also produce from  Imagine Entertainment with Anna Culp as the executive producer and Marja-Lewis Ryan writing. As of January 2019, the project was still in development. In February 2023, it was reported that Sarah Rothschild will write the script.
