THE latest foul-mouthed bro-mantic comedy cast in the Judd Apatow mould is a genuinely funny escapade that milks every guffaw from its predictable fish-out-of-water scenario.

Role Models doesn't deviate once from a well-trodden path of breast gags, wanton stupidity and hard-fought redemption but David Wain's film has an undeniable charm and some terrific one-liners.

The lively patter between leads Paul Rudd, who co-wrote the script, and Seann William Scott, as a pair of puerile 30-something degenerates forced to think like adults for once, wins us over. Inevitably, by becoming mentors to two troubled youths, these men behaving badly grow up and finally lead by example.
