Cinema chain gives Cinderella Man a box office boost

Bosses at cinema chain AMC Theatres across America are so hooked on Russell Crowe's boxing drama Cinderella Man, they're offering to give film fans their money back if they don't like it.

The film has failed to set the box office alight in its four weeks on release in the US and AMC Theatres bosses feel the film "is getting lost" among a host of summer blockbusters.
