A highly amusing and likeable comedy, largely motored by appealing performances from odd couple Paul Rudd and Jason Segel.

Apart from the rude words and frank sex talk, it’s really all quite old-fashioned and down-home.

Rudd’s about to get married, but realises he hasn’t any male friends – let alone a best man! So he sets out to find one, with the help of his gay brother (Andy Samberg) who knows all about guys.

But straight male friends are hard to find and, when you do me across one, he turns out to be the kind of loveable lout (Segel) you might soon want to dump.

With its good idea, funny script, witty lines and a fine set of well-used comedy players, this is a delight.
