The Change-up involves a hectic lawyer father husband (Bateman) swapping places with a single bachelor friend (Reynolds).

This is all far-fetched but it is played for laughs, treading a thin line at times with taste, emotion and it's daft but inevitable scenarios.

This is a rom-com for couples and comedy fans and just about holds onto a safe, silly idea with entertaining license and care-free frivolity.

A good, safe, silly laugh of a film with some good acting thrown in too (Bateman and Mann especially).

The Director (David Dobkin) also has 'Wedding Crashers' and 'I Know Pronounce You Chuck and Larry' on his CV - so expect a mash-up of these 2 films's humour (with mixed results).
