The best movie ever made? Better than 'This is Spinal Tap'

This movie did what no other movie (aside from "Spinal Tap") can no longer do - have me laughing in stitches!

Just in case you're not in on the joke, these guys are putting you on. Phoenix can barely keep a straight face going himself (the beard helps hide it) but Casey Affleck - man, my hat is off to you. You had total mastery of your emotions and facial control throughout this movie. A lesser mortal would have been cracking up, but you kept the straight face going.

Me? I was laughing my a** off the whole time. The question would be "why don't more actors do mockumentaries" and the answer would be "those require talent".
