Birdman is not as advertised. It is not a quirky dark comedy, but a claustrophobically relentless attack on modern-day life. 

Inarritu’s film is an intense combination of the intellectual – akin to Pirandello’s Six Characters in Search of an Author – and visceral – offering an edit-less flow of images that winds through the serpentine backstage hallways and stairwells of a Broadway theatre, only briefly escaping to a bar, a tight balcony and a nightmarish run through Times Square.
