Bobby (15)

By Nicholas Barber

Bobby opens with captions and news footage positing that, in 1968, America was in turmoil, and that Robert Kennedy was the best hope of putting things right. Despite that title, though, Kennedy doesn't appear except on TV screens, and the criss-crossing ensemble drama is influenced just as much by another Robert - the late Mr Altman. It all takes place in the Ambassador Hotel on the day of Kennedy's assassination.

Among the stars who play the hotel's staff and guests, there's William H Macy as the manager, Sharon Stone as the hair stylist, Anthony Hopkins as a retired doorman, Laurence Fishburne as a chef, and Demi Moore, Lindsay Lohan, Ashton Kutcher and the director's dad, Martin Sheen, in other roles. Unfortunately, they're all just mouthpieces for tub-thumping speeches. It makes you wish you were watching a biopic of Robert Kennedy instead.
