MattH, I watched the Billy Wilder thing, the later showing, until I fell asleep. It's kind of slow-going at first. He talks on videotape, mostly in German. It gets going when it gets to some personal recollections, about Monroe, Tony Curtis, etc. There's also a powerful story regarding how the studio wanted to make STALAG 17 palatable to German audiences. There wasn't a whole lot of overly surprising stuff, but it is interesting.
One wishes the interviewer were a little more thorough; the guy interrupts Wilder a few times, but I guess we take what we can get.
