Humphrey Bogart and Cary Grant

"I'm surprised that he got so in bed with him and did not sense that something was hinky," Ferguson says of Bogart. "He's like the guy who's known for like wanting to do acid early with this therapist because he was always after that truth." The actor left no memoir, no based on a true story film, no documentary. He became immortalized on the page by a biography published in 1997 called Romanoff Prince of Rogues.
