The movie's IMDb trivia page has this to say on how Rickman's priceless expression was achieved:

SPOILER: For the shot where Hans Gruber falls from the top of the building, Alan Rickman was actually falling from a 20-foot high model. He was holding on to a stunt man and falling on to an air bag. To get the right reaction, the stunt man dropped Rickman on the count of two, not three.
