There are only a handful of actors in the movie. But all of the teenagers are very good. Those are played wonderfully by Emilio Estevez, Ally Sheedy, Molly Ringwald, Judd Nelson and Anthony Michael Hall. There is also the school's principal played by Paul Gleason which looks suspiciously like Ben Mendelsohn. And there's the janitor with the most wholesome serial-killer smile ever, played by John Kapelos. All these actors know what they are doing very well. And the acting in the movie is pretty much, I think, what holds it together. Because there isn't much else to see, to be honest.
