James McAvoy delivers a commendable performance in the lead role, showcasing a range of emotions from enraged to sorrowful. The supporting cast are modest, though showcase nothing comparable to McAvoy. The film's dark humour is largely successful, though occasionally veers disconcertingly close to uncomfortably perverse.I honestly thought the ending was a spectacular affair, and one of the finest moments of the film.

I came late to this and saw it when it was on Film 4. I was recently amazed by James McAvoy's performance in 'Split' and already adored him as a young Professor X.Seriously, if you haven't seen 'Split', you really should.'Filth' is not for the faint hearted, and is prime fodder for 'Outraged of Halifax' in the Daily Mail comments section.It's a fun ride, like a manic episode can be (I have bipolar and some things felt far too familiar) but then things become tragic, as the depressive phase tends to be. I'm still a little bit miffed about the slightly OTT portrayal of bipolar disorder - it's not a totally accurate account of the illness (hence 9 stars, not 10) - but it's nice to see someone at least try to explore it.The denouement had me sobbing like a 'little bitch with a skinned knee', to quote Jay from 'Dogma' (also a wonderful film you should watch immediately) and the very end was when I really started blubbing.As a Scot and a bipolar type 1, this felt a little too close to home and that's why I adore it. I'm going to be re-watching this as much as I re watch 'Evil Dead 2' and 'Titanic' - yes, I love 'Titanic'. What of it?

I May Be Late In Watching Filth And May Love James Mcavoy But I Must Say This Was One Hell Of A Movie! Loved It, Laughed It And Felt It!!!! Loved Every Character But The Wife. I Had To Read Most Of The Movie's Caption Due To The Obvious Language Barrier: Scotland Vs Texas!?!? But I Truly Laughed My Ass Off During Most Of The Film; Yes, Including The Very Last Moment. THANKS FILTH!!!!•••SIDENOTE, SIDELINE, SIDE SALAD, SIDEBAR: JAMES MCAVOY - My future ex-husband; has a striking resemblance to a picture I saw once of someone, somewhere; and also has my daughters eyes (blue)••• •••So get your restraining order ready because I'm coming to Scotland •••

A man's descent into a drink and drug induced madness and paranoia. Not comfortable viewing and surreal at times. Ironically, the outtakes are some of the scenes that really ought to have been left in, because they are the most touching. A decent adaptation of a truly great book, but as with any adaptation of one of Welsh's novels, it has it's limitations. Each character is played convincingly, a little too convincingly sometimes, but it all comes to bear. The question remains: can a police officer, who is so ravaged by the constant hangovers and come-downs of booze and pills, really find it within himself to apprehend the murderer of a foreign student when the world around him - both physically and mentally - is falling apart?
