Okay, Classic Hollywood movie star knitters in fiction:
How could we forget the sweater Audrey Hepburn attepts to make in Breakfast at Tiffany's?
And the scene in Mr. Lucky where Cary Grant attempts to learn how to knit for War Relief, in an attempt to get the girl (Larraine Day).
Also, I don't know where it's from, but ages ago, someone left me a comment photo on my myspace page of Gary Cooper knitting. (?!)
