Exclusive: Here Comes the Boom trailer

The trailer shows James fail miserably to convert a slam dunk and throwing up all over a fighting opponent. Suffice to say, he doesn't start out as cage fighting material.

Watch the trailer below:

Salma Hayek, Melissa Peterman and 'Happy Days' star Henry Winkler co-star.

'Here Comes The Boom' is released in the UK on 9 November.
