the role, but turned it down. John Cleese also expressed interest for the role, but was deemed not scary enough. Peter O'Toole, F. Murray Abraham, Roddy McDowall, Eddie Deezen and Sting were also considered for the role. Christopher Lloyd was cast because he previously worked with Zemeckis and Spielberg on Back to the Future. He compared his part as Doom to his previous role as the Klingon commander Kruge in Star Trek III: The Search for Spock, both overly evil characters which he considered "fun to play". He avoided blinking his eyes while on camera to portray the character. Fleischer also voiced Benny the Cab, Psycho, and Greasy. Lou Hirsch, who voiced Baby Herman, was the original choice for Benny the Cab but was replaced by Fleischer. Writing Price and Seaman were brought aboard to continue writing the script once Spielberg and Zemeckis were hired. For inspiration, the two writers studied the work of Walt Disney and Warner Bros.

Doom would also have a suitcase of 12 small, animated kangaroos that act as a jury, by having their joeys pop out of their pouches, each with letters, when put together would spell YOU ARE GUILTY. This was also cut for budget and technical reasons. The Toon Patrol (Stupid, Smart Ass, Greasy, Wheezy, and Psycho) satirizes the Seven Dwarfs (Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy, and Dopey), who appeared in Snow White and the
