A cracking story, buzzily edited, this warts-and-warts portrait delivers an illuminating insight into recent rock history. Don't miss it.

Bleakly entertaining, Beware of Mr Baker neither eulogises nor patronises its subject; one day (though possibly not soon), Baker may take it upon himself to say thanks.

It's a broadly forgiving portrait of an impossible, irascible talent, who seems to have treated life much like his instrument.

Instead of a hagiography filled with kind words from old chums, boxer-turned-filmmaker Jay Bulger's documentary, Beware of Mr. Baker, revels in opportunities to present drummer Ginger Baker in all his asshole glory.
