Title: The Bat (1926 film)
Content:  Cinematographer Arthur Edeson, assisted by then-newcomer Gregg Toland, was enlisted to shoot the film. Around the time of filming, much of the film's production was shrouded in mystery, in accordance with the secrecy behind the identity of "the Bat" character, with many of those involved in the filming being obliged to take an oath to not reveal any details of the story publicly and with West disallowing visitors onto the set. West also made his cast work at night, stating that "Given the quiet of the studio at midnight, when no other companies are working, and plenty of spooky music from an orchestra, the players really are in a mood to simulate dark deeds."
Title: Bats (film)
Content:  Bats is a 1999 American horror film directed by Louis Morneau, written by John Logan and produced by Bradley Jenkel and Louise Rosner. The film stars Lou Diamond Phillips, Dina Meyer, Bob Gunton and Leon. It was the first film released by Destination Films. A hostile swarm of genetically mutated bats terrorize a local Texas town, and it is up to zoologist Sheila Casper, who teams up with town Sheriff Emmett Kimsey, to exterminate the creatures before they take more lives. The film grossed $10 million against a $5 million budget. The Rotten Tomatoes critical consensus calls it "neither scary nor creepy".
Title: The Bat (play)
Content:  Marion Jr. Cornelia was played by Emily Fitzroy, and Eddie Gribbon was the Bat. West's wife, Jewel Carmen, played Dale Ogden as her last film role. West made the actors work at night to get them in the mood for the thriller. The film was released by United Artists on March 14, 1926. The year before, West had directed an adaptation of one of The Bat imitators, The Monster. Critics considered The Bat to be an improvement over that previous film; it received positive reviews and did well at the box office. The film was considered lost for decades, but a print was discovered in the 1980s. Following the commercialization 
Title: The Bat (1959 film)
Content:  RKO Pictures bought the rights to remake The Bat from Mary Pickford, who produced the original 1926 film adaptation for United Artists, the studio she founded in 1919 with Douglas Fairbanks, Charles Chaplin and D. W. Griffith. The Bat was released as a double feature with the Hammer horror film The Mummy.
Title: The Bat (play)
Content:  The play's lead role is Cornelia Van Gorder, played in the first production by Effie Ellsler. Despite The Bat unusually long run, Ellsler appeared in almost every performance (including the evening after she heard about her husband's death); she left the part only briefly, after collapsing onstage during the production's final week. The Bat was her last Broadway role. Wagenhals and Kemper cast Harrison Hunter in the play's title role. They did not show Hunter or the other cast members the final scene (in which the Bat's identity is revealed) until shortly before the dress rehearsal. Hunter, who had thought he was playing a detective, was upset to learn that his role was that of a criminal, although

Title: The Bat (1926 film)
Content:  The Bat is a 1926 American silent comedy mystery film directed by Roland West and starring Jack Pickford and Louise Fazenda. The film is based on the 1920 Broadway hit play The Bat by Mary Roberts Rinehart and Avery Hopwood, which itself was an adaptation of Rinehart's 1908 mystery novel The Circular Staircase.
Title: The Bat (1926 film)
Content:  Director Roland West was reportedly a huge fan of Rinehart's stage play The Bat. So much so, that when initial negotiations to purchase the rights to the play fell through, he became inspired to instead direct an adaptation of another horror-themed stage play, called The Monster. On September 11, 1925, The Film Daily reported that Roland West had purchased the rights to the play for $75,000 with the intent to produce a film version. On November 4, 1925, The Film Daily reported that Julien Josephson had completed the screenplay adaptation of The Bat. The Trade Review reported that Josephson allegedly had "written the screen story of The Bat without changing the general plot, but

Content:  added mystery complications calculated to baffle even the hundreds of thousands who have seen the stage play,” with West going so far as to claim that "The picture will be a complete surprise even to those who have seen the stage play." The prop department was directed by Ned Herbert Mann, who constructed the miniatures for the film: the buildings and "the Bat" in flight. The interior of the mansion was constructed at the United Artists' Hollywood sound stage under the direction of William Cameron Menzies. Scenic artist Harvey Meyers was enlisted to paint shadows on the sets to enhance the somber atmosphere of the more suspenseful, dark scenes that are later into the 
Title: Bat Pussy
Content:  Bat Pussy is an American pornographic film, believed to have been produced and possibly released in the early 1970s. Ostensibly a spoof of the 1966–1968 Batman television series, it has been cited as the earliest example of a pornographic parody film and more infamously considered to be the worst pornographic film ever made. Released in relative obscurity and near-anonymity, Bat Pussy was discovered in the storeroom of a Memphis, Tennessee Adult movie theater in the mid-1990s and subsequently issued on home video by exploitation film distributor Something Weird Video. No credits or copyright information can be found on this print, and as a result, nothing is known for certain about its production or who was involved; it is not known who made the film or even stars in it. Since its video release, it has attracted a cult following among exploitation and pornography fans for its notoriously poor quality, with most reviews criticizing its technical flaws, bizarre dialogue, and the sexual ineptitude and physical unattractiveness of its lead actors, who are known only by the names they receive in the film itself.
