Seems the wolfpack has finally come full-circle and are heading back where it all began for The Hangover Part 3. Yep, the boys are almost ready to get back to business, and we can't wait. The Hangover Part 3 sees the lads returning to Vegas in a bid to save poor old Alan from himself.

Y'see, his dad has died and he's gone a wee bit crazy with grief, leaving the boys with no option but to intervene, with errr, lets just say consequences. Bradley Cooper, Zach Galifianakis and Ed Helms are back in action, as are Justin Bartha, Ken Jeong, Jamie Chung, Heather Graham and Mike Tyson, who will all reprise their roles from the previous films. Keep your eyes peeled for John Goodman and Melissa McCarthy, who join the cast for this third and final (yeah, we're sure if it does well enough there will be another) installment.

Catch The Hangover Part 3 in cinemas from May 24th.
