Here are first-looks at a couple of highly-anticipated American productions. Darren Aronofsky returns from his The Wrestler triumph with the psychological drama Black Swan, which stars Natalie Portman and Milas Kunis as a pair of rival ballet dancers. It will open the Venice Film Festival in September.

I'm Still Here is Casey Affleck's documentary about Joaquin Phoenix's decision to quit acting in favour of a career in rap. Hoax or not? Either way, it will be debuting at the Toronto Film Festival next month.
