Finished it last night. Add these ones to the list:
Exorcist Apocalypse now Matrix Star Wars Aliens
Slight spoilers below:
To answer an above poster's question, as mentioned Jaws was parodied most notably at the part where the Dogfish chases you up the dock.
The Untouchables was parodied in the cut scene directly after you finish with Rock Solid and before you go on the Bomb run to destroy the Uga Buga's. When the mob boss beats the weasle to death at the table, during the meeting, it's taken directly from the Untouchables when Robert DeNiro (as Al Capone) does the exact same thing.
