The commentary for Spinal Tap where they’re in character is hysterical, “He’s dead now.” “Will you stop saying that?”
All the Bruce Campbell and Sam Raimi commentaries are funny as hell. “Hit Bruce again, he likes it.”
But the commentary for Spaceballs was a HUGE letdown. Apparently, it’s just a rip from the old laserdisc and Mel Brooks is just randomly going on like someone’s grandfather.
During the commentary for X-men 1.5, in the scene where Bobby is telling Rogue that she’s in trouble (this is right after her getting stabbed by Wolverine) Bryan Singer says that he’s had a lot of fans congratulate him on the small detail of having Bobby’s (aka Iceman) breath be visible, but Rogue’s not. In fact, it was just a cold Toronto morning when they shot that scene, and Anna Paquin’s angle was filmed when it was slightly warmer.
Plus the fact that it was actually Mystique pretending to be Bobby at that point in the movie.
