1. -   Rudy Vallee, The Bachelor and the Bobby Soxer   (UK: Bachelor Knight), 1947. Having written the film as his Hollywood comeback after WWII, Sheldon was pushed into a screentest when Cary Grant suggested him as the perfect second male lead. "Since   I'd written the script, I felt confident that I knew all the lines and could do justice to them. But when Cary fed me my cue, I looked up and saw all the fellows up on the catwalks and behind the cameras - and froze! Next thing, I was running out of the studio." A failure...   who went on to pen 250-plus tele-scripts, 25 movies, six Broadway plays, and a dozen novels with 200 million sales!.
