Dismal, ghastly film...
Proceed directly to video. Do not pass Go, do not collect £200.
First off - where did anyone get the idea Billy Murray could act? He was fine in the background as an extra in the Sweeney from time to time, but he shouldn't be allowed to utter any words on film ever again.
As for the rest of the cast - risible. The funniest bit of miscasting is the solicitor - he's clearly an actor in his twenties, but they've tried desperately to make him look older by painting white stripes in his hair around his ears. Yeah, that'll work. Now he looks fifty.
Then there's the big lady crime boss, who would be more suited behind the till in Tesco. Oh, and the whole point of polythene is not to walk all over it and tread blood around when you've topped someone.
As for this being a 'true' story? Only if you also believe in Santa and the tooth fairy...
