Generally frightening (and brutally honest) human Rob Zombie will transition out of the horror genre to make a biopic about the end of Groucho Marx’s life, Deadline reports. For real. The movie will be based on Steve Stoliar’s memoir Raised Eyebrows: My Years Inside Groucho’s House, which details the life of a young Marx Brothers fan who worked as the comedy luminary’s personal secretary and archivist. “I have been a huge Groucho Marx fan ever since I was a child and have read countless book on the comic legend, but after reading the book Raised Eyebrows, a totally new perspective on Groucho’s life emerged,” Zombie, who will collaborate with scribe Oren Moverman, said. “I immediately saw this project as Groucho’s Sunset Boulevard and knew I had to bring it to the big screen.” Fair enough. Let’s get Marx-weird, man.
