The Beast Will Have Its Day
A small fraction of the budget, none of the hype, and only one genre, and I still think that Joe Johnston's (Jurassic Park III, October Sky) Wolfman trailer beats the pants off of James Cameron's Avatar trailer. Wolfman has two things that Avatar does not: Benicio Del Toro and a fucking werewolf. And from the looks of it, a pretty goddamn good one.
It's been a long while since we've seen a good werewolf movie. I wouldn't necessarily count on this one to save the day -- it's had a lot of production problems, and has been pushed back several times. It's not set for February, which doesn't exactly inspire a lot of hope. But the transformation scenes featured in the trailer, do.
I'd still see it before Avatar.
