A new biopic about famed Tonight Show host Johnny Carson is in the works, Deadline reports. The movie will be based on author Bill Zehme’s upcoming book Carson the Magnificent, which was supposed to be released in 2006 but has since been delayed several times. Zehme was the only journalist Carson spoke to after his retirement. The book will be adapted into a screenplay by John McLaughlin (Hitchcock, Black Swan), but the details of the film’s focus are murky as Carson always kept his private life private. Needless to say, Zehme probably got some info from Carson that we all don’t know about, otherwise this is gonna be a really boring biopic. No director or star are in place as of now, but you can bet Dana Carvey’s dusting off an old white wig right about now.
