A funny thing happened when I learned to knit: I began to notice knitting--the act, the results, the supplies. When I got tired of pestering my family to come see so-and-so knitting on tv, I decided I'd just make myself a list.
Everytime I caught sight of a knitter in a movie, I wrote it down. In some cases, knitting was just something a character did (Top Hat, My Man Godfrey, They Wanted to Marry).
But in others, knitting was integral to the character's identity or to the development of the movie's plot:
"Robin and the Seven Hoods"
"I Was a Male War Bride"
"Breakfast at Tiffany's"
" Willy Wonka and the Chocolate Factory"
" Mr. Lucky"
" The Mouse That Roared"
"Shall We Dance"
"Wallace and Gromit: The Curse of the Were-Rabbit"
"After the Thin Man"
And when there's knitting, in a WWII storyline, in a movie, well! This gal's in hog heaven, as we used to say in Texas. Any knitting specifically for the war effort naturally ranks high on my list(I Was a Male War Bride, Mr. Lucky).
My husband pointed this one out to me, but I'm not sure if it should count: the scene in "A Night at the Opera" where Harpo is pretending to knit with two forks and some fringe from the tablecloth draped over his shoulders! Maybe we could just classify that as "Marxian" knitting! Ha!
These are only the recently discovered, mind you. There's no telling how many escaped my notice in my pre-knitting days. And since I often knit while watching movies, I might be missing some crucial scenes even now!
