Here's a nugget of camera-related trivia about Die Hard, my favourite movie for many, many years. (Only pushed into second place by Fight Club.)

From the Internet Movie Database's trivia page:

When the bomb in the elevator shaft blows out the side of the building, the effect was accomplished by (a) collecting virtually every camera flashbulb of a particularly powerful type in the Los Angeles area and wiring them on the outside of the actual building to simulate the flash, and (b) by superimposing a shot of an actual explosive blowing a hole in the wall of an all-black miniature of the building at the appropriate location.
