Warner Brothers 1996
Director: Tim Burton
Barry was Head Animator until the production was changed to CG
Tim Burton initially intended to use stop motion animation to feature the Martians, viewing it as a homage to the work of Ray Harryhausen, primarily Jason and the Argonauts. Similar to his own Beetlejuice, Burton "wanted to make [the special effects] look cheap and purposely fake-looking as possible"....
Burton hired Barry Purves to shepherd the stop-motion work. Purves created an international team of about 70 animators, who worked on Mars Attacks! for eight months and began compiling test footage in Burbank, California. The department workers studied Gloria Swanson's choreography and movement as Norma Desmond in Sunset Boulevard for inspiration on the Martians' movement.
When the budget was projected at $100 million (Warner Bros. wanted it for no more than $75 million), producer Larry J. Franco commissioned a test reel from Industrial Light & Magic (ILM), the visual effects company he worked with on Jumanji. Burton was persuaded to change his mind to employ computer animation, which brought the final production budget to $80 million. Although Purves was uncredited for his work,... Ian Mackinnon and Peter Saunders, who would later collaborate with Burton on Corpse Bride, received character design credit.
