Infidelity is a tricky subject, and inherently cinematic. It’s no surprise there’s been a number of films made about it, but it’s also no surprise that most of these films aren’t good. The latest film to tackle it is called Last Night, it stars Keira Knightley, Sam Worthington, Eva Mendes and Guillaume Canet, was directed by Massy Tadjedin, and will be released on May 6. There’s a trailer for the film – which was lost in the shuffle of Miramax being sold – and it suggests a romantic drama about a couple (Worthington, Knightley) put in positions to have affairs.

This sort of film looks tricky, and it’s easy to see why the film was not a high priority for release. With independent films you can either sell them or not, and this doesn’t seem to have a pleasant hook – though it does have three stars in it. This is likely why it’s being pushed out for theatrical and Video on Demand. It’s always fascinating to see which films get tucked away by studios, films that don’t work, and in the Weinstein-Miramax days there were numbers of films that took years to finally see the light of day. All things, this hasn’t sat around that long.

Since the film is being shown at the Tribeca film festival, that may have helped get the film out there, as it’s being distributed by Tribeca film. As art-house fare these days  – unless it leaves that festival getting great love and affection – it’s more than likely D.O.A.

The other interesting thing about this film is that it stars Sam Worthington. Having starred in one of the most successful films of all time (Avatar) he’s yet to turn himself into an audience favorite. And though he’s been in big-budget movies that have made money, he’s also had to apologize for their faults. Worhtington’s spent some time doing indie film work, but it still feels like he doesn’t have a career plan, unlike – say – Leonardo DiCaprio.

Do you think this be the Last Night of their relationship?
