someone here on KH (my over-used brain can't remember who) has an avatar of cary grant knitting, but they couldn't remember where they got it. i was just looking at the Classic Flicks group on ravelry and discovered that it's from
Mr. Lucky. apparently his character turns into an obsessive knitter.

of course, the movie hasn't been released on DVD or VHS, but we can always hope. someone posted that TCM shows it from time to time.
