Had it hanging around from LoveFilm for weeks, finally watched it last night.
Properly good cast: James McAvoy, Mark Strong, Andrea Riseborough, Peter Mullen, David Morrissey, Daniel Mays, Natasha Little. And a guy who I'd not seen before called Johnny Harris who was brilliant: I genuinely had to check the credits to make sure it wasn't Paddy Considine.
London has rarely looked better - some cracking location shots and aerials.
Only problem was that the story doesn't quite hang together. And, for me, there is a little too much reverence for John Woo-style Hong Kong gangster films.
Not bad though: 7/10
