Harrison Ford was Spielberg's original choice to play Eddie Valiant, but his price was too high.[18] Chevy Chase was the second choice, but was not interested.[19] Bill Murray was also considered for the role, but due to his idiosyncratic method of receiving offers for roles, Murray missed out on it.[20] Eddie Murphy reportedly turned down the role as he misunderstood the concept of cartoon characters and human beings co-existing; he later regretted this decision.[21][22] Several other actors were also considered for it, including Robin Williams, Robert Redford, Jack Nicholson, Sylvester Stallone, Wallace Shawn, Ed Harris, Charles Grodin, and Don Lane.[19] To facilitate Hoskins' performance, Charles Fleischer dressed in a Roger Rabbit costume and "stood in" behind camera for most scenes.[23] Animation director Williams explained Roger was a combination of "Tex Avery's cashew nut-shaped head, the swatch of red hair... like Droopy's, Goofy's overalls, Porky Pig's bow tie, Mickey Mouse's gloves, and Bugs Bunny-like cheeks and ears."[12] Kathleen Turner provided the uncredited voice of Jessica Rabbit, Roger Rabbit's wife.[24] Tim Curry originally auditioned for the role of Judge Doom, but afterward, the producers found him too terrifying.[25] Christopher Lee was also considered for it, but turned it down.[19] John Cleese also expressed interest for the role, but was deemed not scary enough.[19] Several other actors were also considered, including Peter O’Toole, F. Murray Abraham, Roddy McDowall, Eddie Deezen, and Sting.[19] 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 being overly evil characters which he considered being "fun to play".[26] He avoided blinking his eyes while on camera to perfectly portray the character.[13] 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.[23] <i>Who Framed Roger Rabbit</i>
