John Waters once remarked that no movie should be longer than 90 minutes. While I could easily lead the chorus of outraged objections what about The Godfather? Gone With the Wind? Titanic? Dances With Wolves? (come to think of it, scratch that last one) can we all admit that Waters had a point? Too many movies today are far too long, and the raging elephantitis doesn't merely inflate action duds like Stealth or indulgent comic-book spectacles like Sin City. It extends even to a comedy as nimble as Wedding Crashers, which is so much more clever and romantic than its horny chortle of an ad campaign would lead you to expect, and deserved a leaner, meaner shape (did we really need to see Owen Wilson bottom out at the end for 20 minutes?) to accommodate its blithe screwball spirit.
