Morris made a big splash in Hollywood, and a lot of money, in 2007. That is when he negotiated a landmark deal that gave the creators of “South Park,” Matt Stone and Trey Parker, a precedent-setting 50 percent stake in the cartoon’s success in digital media. Morris had met the pair years earlier when they were relatively little-known filmmakers, and he represented them for the next few years for free. He later produced a musical, “The Book of Mormon,” that the pair had written with a third partner for which he won a Tony Award. Mr. Morris has also written a show-business satire called “Gettysburg,” a semi-autobiographical coming-of-age tale titled “All Joe Knight,” and a collection of short stories. As a young man, Mr. Morris worked as an office assistant for a member of the British Parliament. A company Mr. Morris started last year called Media Courthouse Documentary Collective, is producing films on subjects including cryptology, Congress and the unfolding defamation case brought by Johnny Depp against his ex-wife, the actress Amber Heard.
