Ohhh yeah, Powell and Pressburger, of course. :-D And, like...Thelma Schoonmaker and Martin Scorsese, which I know they don't work as equal partners exactly, but she's his editor, right? IMDb says she's done every film of his since "Raging Bull," so yeah, that's a powerful relationship right there.

I think it might be about letting other people keep you honest, or something. I'm not sure.
