Because it just needs to happen, the Coolidge is showing "Brokeback Mountain" tonight at 7pm. The layers of tragedy will, over time, accumulate around this imperfect movie and its great, deep performance -- and its greatish, deepish ones, too -- until everything about them assumes the impression of wisdom. We'll search this movie and Ennis Del Mar the way we might someone else's soul. We leave a little more devastated, a little more lost than we did the first time. You'll watch Heath Ledger and think the ache in his heart and in his bones seems realer, more contagious. Bad news has a way of doing that to an already iconic piece of acting. Have you seen "Rebel Without a Cause" lately? Of course, the Coolidge could just as easily have shown "Casanova" to remind us that the world has lost this happy, horny dude, too.
