You know, it's really odd when you hear sounds from a game in another game or movie. For instance, in http://www.youtube.com/watch?v=4UqFPujRZWo, at 2:05 she blasts the annoying thing with a spell and the sound is the same for casting a spell in DF. Another one that I remember was at the very beginning of Moll Flanders (terrible movie, but) they open a door to her cell and the sound was the very same creaky door sound that we've all come to know and love from our dungeon diving.
Any others? I swear that Warcraft II and DF used the same pig sounds.
