Who Framed Roger Rabbit [SEP] Introduction
Price and Seaman wrote two drafts of the script before Disney brought in executive producer Steven Spielberg and his production company, Amblin Entertainment. Zemeckis was brought on to direct the film while Canadian animator Richard Williams was hired to supervise the animation sequences. Production was moved from Los Angeles to Elstree Studios in England to accommodate Williams and his group of animators. While filming, the production budget began to rapidly expand and the shooting schedule ran longer than expected. The film was released through Disney's Touchstone Pictures banner on June 22, 1988. It received acclaim from critics, who praised its visuals, humor, writing and performances.
