The writer-director talked about his new project at British Academy of Film and Television Arts' Screenwriters Lecture in September.
"I always try to do something that I don’t know how to do, and I always try to do something different," said Kaufman in his speech. "This thing that I just wrote, that hopefully is going to get made, is a musical. I’ve never done that before, so I did it."
According to Indiewire, Nicolas Cage, Jack Black and Steve Carell are attached to the project. The film will be about online film criticism and includes such characters as a writer-director, whose movie is nominated for a record-breaking 29 Academy Awards; a comedian typecast as an overweight slob; a film blogger who has built a cult following; and Robert, a "robot-head" who has worked out the formula for a perfect script.
"The reason it’s a musical is because I have a tendency to write very interior things," said Kaufman. "And, I’m always trying to figure out a new way to express that."
Kaufman won an Oscar for Best Original Screenplay for "Eternal Sunshine of the Spotless Mind." His other film work includes "Being John Malkovich," "Human Nature," "Adaptation" and "Synecdoche, New York." To read Kaufman's full speech, click here.
