I recently spent a weekend watching Meatballs, Stripes, and Ghostbusters “with” Ivan Reitman and Daniel Goldberg. They have great affection for these movies, and it comes across in the commentary. And, without fail, this affection extends to the cast and crew. Call it a “feel good” DVD extra.
Mel Gibson’s commentary to Apocalypto is similar in that he gives full credit to the people who helped him make the movie. (He gets a few digs in on the historical nitpickers, too.) Say what you will about Mel, but he makes it clear how proud he is of his team, and I think that shows some class.
