You might not expect a foul-mouthed, crunchingly violent and darkly comic oddball film about hitmen to make you stop and consider life, honour and the nature of purgatory but that's exactly what In Bruges achieves.

Meet Ray (Colin Farrell) a newbie contract killer who is eaten up with guilt because his first job has seen him accidentally murder a small boy.

He's hiding out in the quiet fairytale-ike Belgian town of Bruges with his fellow hitman/mentor Ken (Brendan Gleeson) – both of whom could be in serious trouble with their nasty boss Harry (Ralph Fiennes).

From the initial bickering about being holed up in the middle of nowhere with sightseeing the only real option, things get progressively weirder by the moment in this hard to classify movie that straddles genres.

There is so much happening here - one minute you'll be laughing at dubious kung-fu violence being inflicted on a coked-up dwarf and the next pondering the afterlife thanks to Hieronymus Bosch's classical painting The Last Judgement.

Writer/director Martin McDonagh peppers the script with moments of sublime banter (none of which is in very good taste but is liable to make you grin) eg Ken tells Ray: "You are the worst tourist," to which Ray responds: "Look, Ken. I grew up in Dublin, and I love Dublin. If I had grown up on a farm, and was retarded, Bruges might impress me. But I didn't, so it doesn't."

Or as a Spurs fan - my favourite line in which Ray sums up purgatory as: "It's when you're not awful, not really bad, but you're not really good either – a bit like Tottenham."

And that kind of fittingly sums up the film too. I guarantee one thing; you won't see a stranger neo-noir crime comedy hitman saga this year.

Farrell and Gleeson are a very watchable duo who take the wacky plot twists in their stride whilst skating on the surface tension of their misdeeds and the potential repercussions thereof.

I'm already looking forward to the mooted sequel 'In Biggleswade', which sees another two hitmen (possibly George Clooney and Bruce Willis) hiding out in Bedfordshire's cosmopolitan metropolis.

Apparently they get to contemplate life, death and confront their inner demons while doing a spot of shopping in the Market Square before taking a short course at Shuttleworth College.
