Oliver replaced the WWII subplot with Roger's inadvertent rise to stardom on Broadway and Hollywood. Disney was impressed and Alan Menken was hired to write five songs for the film and offered his services as executive producer. One of the songs, "This Only Happens in the Movies", was recorded in 2008 on the debut album of Broadway actress Kerry Butler. Eric Goldberg was set to be the new animation director, and began to redesign Roger's new character appearance. Spielberg became busy establishing DreamWorks, while Frank Marshall and Kathleen Kennedy decided to remain as producers. Test footage for Who Discovered Roger Rabbit was shot sometime in 1998 at the Disney animation unit in Lake Buena Vista, Florida; the results were a mix of CGI, traditional animation, and live-action that did not please Disney. A second test had the toons completely converted to CGI, but this was dropped as the film's projected budget would escalate past $100 million. Eisner felt it was best to cancel the film. In March 2003, producer Don Hahn doubted a sequel, arguing that public tastes had changed since the 1990s with the rise of computer animation. "There was something very special about that time when animation was not as much in the forefront as it is now." In December 2007, Marshall stated that he was still "open" to the idea, and in April 2009, Zemeckis revealed he was still interested. According to a 2009 MTV News story, Jeffrey Price and Peter S. Seaman were writing a new script for the project, and the animated characters would be in traditional two-dimensional, while the rest would be in motion capture. In 2010, Bob Hoskins had agreed to sign on for a sequel, but expressed scepticism about the use of "performance capture" in the film. Zemeckis said that the sequel would remain hand-drawn animated and live-action sequences will be filmed, just like in the original film, but the lighting effects on the cartoon characters and some of the props that the toons handle will be done digitally. Also in 2010, Hahn, who was the film's original associate producer, confirmed the sequel's development in an interview with Empire. He stated, "Yeah, I couldn't possibly comment. I deny completely, but yeah... if you're a fan, pretty soon you're going to be very, very, very happy." Hoskins retired from acting in 2012 after a Parkinson's disease diagnosis a year earlier, and died from
