The film - directed by the man behind Hairspray - mixes a classic romance storyline with the plight of washed up rocker Stacee Jaxx - and it's all set to a whole host of ROCKING tunes.
Think Glee, Hairspray and a Rolling Stones concert all mixed in to one. Yeah, we know it's difficult to imagine.
The all-singing, all-dancing cast includes Russell Brand (obvs) and the more unlikely Tom Cruise - trust us when we say this is a Tom you’ve NEVER seen before.
Watch the trailer below and tell us what you think… we’re just off to get our hair cut in to a mullet.
