Continuity mistake: When they have just poisoned Charles Durning, Mark the painter falls to the floor pretending to be sick. During this scene the stopper in one of the bottles is out, then it's back in, then out and so on.
The Last Supper (1995)
Ending / spoiler
Directed by: Stacy Title
Starring: Cameron Diaz, Annabeth Gish, Ron Eldard, Jonathan Penner
The infamous politician (Ron Perlman) is the last guest that Cameron Diaz and the other roommates have dinner with. While they're discussing whether to kill him or not, he looks around the house and figures out that they're the ones responsible for the missing people and then slips some of the poisoned wine into their cups. The last scene is a painting of one figure with a blue bottle (the one with poisoned wine) and around him are five dead people with a voice over of the politician announcing that he's interested in running for president...

Luke: People disappear all of the time.
Jude: Especially in Iowa. We probably saved him from an alien abduction.
