James McAvoy is a charming and talented actor who’s done nothing but good work up to this point, so it was probably about time someone rewarded him with a role that allowed him to engage in casual sex, guzzle copious amounts of booze, and snort up enough drugs to kill a donkey. And, as you can see from the film’s brand new trailer, Jon S. Baird’s adaptation of Irvine Welsh’s “Filth” has provided him with just that sort of role. Given all of the sex, boozing, and drugs going on though, the trailer is marked as restricted, so don’t go trying to sneak any peeks if you’re under age. For the rest of you, enjoy, and try to make note of the fact that Filth looks like it’s going to be much more than just a shallow wallowing in bad behavior. This is a story from the same guy who wrote “Trainspotting,” after all, so there’s bound to be some pathos mixed in with the partying. McAvoy’s pervert, junkie cop character seems to be the complex sort of gent who’s struggling with a lot of issues, so this should be a role that’s both fun to play and worthy of his considerable talents. Give the fast-paced trailer a whirl for yourself and see if you can spot familiar faces like Imogen Poots, Jamie Bell, and Jim Broadbent in the midst of all the madness.
