Thanks Supercereal!

The unknown Eric Stoltz film I posted about earlier is most likely "Don't Look Back", which, according to imdb included Sunset Boulevard as a filming location. Thanks to Supercereal for the tip in the comments.
So, has anyone actually seen this movie?
Incidentally, the building where I worked in Canoga Park can be seen several times in the Alicia Silverstone movie Blast from the Past.
Also, my wife is probably among the extras in the Arnold Schwarzenegger film Jingle All the Way (there were a lot, and they all had big coats on). She wasn't a paid extra, she simply snuck on the set during her lunch break a few times and even spoke with the Arnold a time or two. It used to be very easy to sneak onto the Universal lot and wander around unaccompanied. That's how Steven Spielberg got his start there (at least according to legend).
