Victor Navone (born November 2, 1970) is an American animator, artist, and director.
 He is best known for his animated clip "Alien Song" as well as his character animation at Pixar Animation Studios for feature films including "Monsters, Inc.", "Finding Nemo", "The Incredibles", "Cars", and "WALL-E".
 In 2008, Navone won a Visual Effects Society award for Outstanding Animated Character in an Animated Motion Picture for the WALL-E and EVE truck sequence.
 He shared the award with Jay Shuster, Austin Lee, and Ben Burtt.
Melody Time was an early Australian music television series which aired in 1957 on Melbourne station ABV-2 (it does not appear to have aired in Sydney).
 The live show was hosted by singer Ormonde Douglas, who also made guest appearances on other Australian television series of the era.
The Submarine Voyage was an attraction at Disneyland in Anaheim, California.
 The attraction, which featured ride vehicles designed to resemble submarines, opened on June 14, 1959, as one of the first rides to require an E ticket.
 It was part of a major expansion of Tomorrowland and Fantasyland, which also included the Matterhorn Bobsleds roller coaster, an expanded version of Autopia, the Disneyland Monorail, and the Motor Boat Cruise.
 The Submarine Voyage closed on September 9, 1998; at that time, it was reported that the attraction would reopen with a new theme by 2003, but that did not occur.
 The attraction ultimately reopened in June 2007 themed to Disney·Pixar's "Finding Nemo", and now operates as Finding Nemo Submarine Voyage.
Trust Issues with Magicians is the second of two demos created by Welsh pop punk band Kids In Glass Houses.
 The demo featured "Telenovela", and a track which has not been released elsewhere yet, "Flirting With Widows" (which can now be found through various P2P Networks).
 The demo was sold as various gigs and was also handed out for free on Tesco copy CDs featuring simply 'KIGH' written in marker on the CD along with being given away with candy canes in one case.
 This one case was at a Christmas special gig in Clwb Ifor Bach, which also featured fellow Welsh bands Dopamine, The Blackout, Covergirl and These Radio Days.
Toy Story Toons: Partysaurus Rex is a 2012 Pixar computer animated short film directed by Mark Walsh.
 It was first screened in theaters ahead of the 3-D theatrical re-release of "Finding Nemo".
 "Partysaurus Rex" is the third short in the "Toy Story Toons" series, based on the characters from the "Toy Story" feature films.
 The short involves Rex getting left in the bathroom and making friends with bath toys.
 It is one of the final roles of Don Rickles as Mr. Potato Head, before his passing in 2017, followed by "Toy Story of Terror!
", "Toy Story That Time Forgot" and "Toy Story 4".
Melody Time (working title All in Fun) is a 1948 American live-action animated film and the 10th theatrically released animated feature produced by Walt Disney.
 It was released to theatres by RKO Radio Pictures on May 27, 1948.
 Made up of several sequences set to popular music and folk music, the film is, like "Make Mine Music" before it, the popular music version of "Fantasia" (an ambitious film that proved to be a commercial disappointment upon its original theatrical release).
 "Melody Time", while not meeting the artistic accomplishments of "Fantasia", was mildly successful.
 It is the fifth Disney package film following "Saludos Amigos", "The Three Caballeros", "Make Mine Music", and "Fun and Fancy Free".
Shark Bait (The Reef: Shark Bait in the UK, Australia and North America, Pi's Story in South Korea) is a 2006 South Korean-American computer animated film.
 The plot revolves around Pi and his attempt to win the heart of Cordelia while dealing with a tiger shark that is terrorizing him and the reef's inhabitants.
 The film was a commercial failure.
 It was largely criticised for borrowing heavily from other films such as Disney/Pixar's "Finding Nemo", DreamWorks' "Shark Tale", and Walt Disney's "The Little Mermaid" (and at one point, a reference to "Star Wars" and "The Karate Kid"), and despite the talented actors and comedians involved in the voiceover work, was a box-office bomb.
 Despite being an American-South Korean co-production, the movie did not receive a theatrical release in the United States, where it was released direct to DVD in 2007.
Jacek Kawalec (born 22 September 1961 in Warsaw) is a Polish actor, game show and television personality.
 He gained popularity as a host of one of the first American shows to be licensed and remade to be broadcast on Polish television - 'Randka w ciemno' (the format of The Dating Game).
 After he quit the show in 1998, due to a fire accident which was broadcast live, Kawalec became as a dubbing actor in animated motion pictures with leading roles in such hits as 'Gdzie jest Nemo?'
 (Finding Nemo) or 'Epoka lodowcowa' (Ice Age).
 Later on, he was offered a role in a popular TV series 'Ranczo' and his face became well known again in Poland, as he created a character of a local teacher of Polish literature.
Finding Nemo is a 2003 American computer-animated family film produced by Pixar Animation Studios and released by Walt Disney Pictures.
 Written and directed by Andrew Stanton with co-direction by Lee Unkrich, the film stars the voices of Albert Brooks, Ellen DeGeneres, Alexander Gould, and Willem Dafoe.
 It tells the story of the overprotective ocellaris clownfish named Marlin who, along with a regal blue tang named Dory, searches for his abducted son Nemo all the way to Sydney Harbour.
 Along the way, Marlin learns to take risks and comes to terms with Nemo taking care of himself.
Exploring the Reef (2003) is a live action/computer animated humorous short documentary film included on the second disc of the "Finding Nemo" DVD.
 It features Jean-Michel Cousteau in a documentary film he is trying to make about coral reefs, but Marlin, Dory and Nemo keep interrupting him.
