With just over two and a half months until its release, the much-anticipated conclusion of the bachelor-partying trilogy The Hangover Part III has finally unveiled its first (and rather humourous) trailer.

The final installment sees our ill-fated trio of Phil (Bradley Cooper), Stu (Ed Helms) and Alan (Zach Galifianakis) deciding to journey towards their former stamping ground Las Vegas (the setting of the first film) though this time there are no bachelor parties or weddings. Instead the focus will be on Alan as he struggles to cope with the death of his dad Sid (Jeffrey Tambor).

Director Todd Phillips continues to work behind the camera while a host of original Hangover characters are back including Doug (Justin Bartha), Mr Chow (Ken Jeong), Jade (Heather Graham), Lauren (Jamie Chung) and another small role for ex-boxer Mike Tyson.

There are also brief glimpses of newcomers John Goodman (The Artist, Argo) as a potential villain and Melissa McCarthy (Bridesmaids, This is 40) as an unusual woman who shares a connection with Alan.

The Hangover Part III will be released in UK cinemas on 24th May.

It’s gonna be a sick ending bitches!
