WB has released a Behind-The-Scenes Featurette on the filming of the final chapter of The Wolf Pack series, "The Hangover: Part III," starring Phil (Bradley Cooper), Alan (Zach Galifianakis), and Stu (Ed Helms), as three best friends that anyone could have. Todd Phillips' epic conclusion starts with the death of Alan's father, which takes a serious toll and drives Alan to excessive drinking -- which, incidentally, leads to the accidental death of a giraffe. Looking to cheer up their pal before sending him to a rehabilitation center, the pack decides to have one last hoorah at the place where it all started, Las Vegas.
This time, there's no wedding. No bachelor party. What could go wrong, right? But when the Wolfpack hits the road, all bets are off.
The Hangover: Part III stars Bradley Cooper, Zach Galifianakis, Ed Helms, Justin Bartha, John Goodman, Melissa McCarthy, Heather Graham, Jamie Chung, Jeffrey Tambor, Mike Epps, Mike Tyson, Ken Jeong
