Here’s a prescription for David Cronenberg: never make us go four years without a new film again. It’s felt like an eternity since Cronenberg’s gangbusters thriller Eastern Promises — indeed, it’s the longest hiatus from the big screen in the director’s career — but now there’s finally a trailer for his follow-up, the erotic drama A Dangerous Method. The movie stars Michael Fassbender and Viggo Mortensen as strangely good-looking versions of Carl Jung and Sigmund Freud, respectively, whose bond is tested when Fassbender takes in Keira Knightley as his patient and decides to get very hands-on with her. The two engage in a torrid affair full of enough kinky sex and rough stuff to inspire several Rihanna videos, and Vincent Cassel is there, too, just in case you needed a little more highbrow, art-movie eroticism. Spanking! Canes! Interesting facial-hair choices! Risky attempts at foreign accents! Are you in? [Coming Soon]
