Michelle Williams and Ryan Gosling at Cannes Film Festival 2010This year's Cannes isn't exactly overwhelmed with recognisable Hollywood names, so I made a point of seeing Blue Valentine today, starring Ryan Gosling and Michelle Williams (pictured here arriving in Sunny Cannes). It was playing in the Un Certain Regard sidebar, its relatively lowly berth attributable to the fact that.the film has already premiered in Sundance.

It's a highly affecting US indie flick about a nurse (Williams) and a house painter (Gosling) and their young daughter, flashing back to how they first met and got together. It's one of several films in Cannes to feature quite raunchy sex, which may prove a selling point at the box-office.
