Check out the official trailer…

“Someone needs to burn this place to the ground.”

Wise words from Ed Helms in the first video from “The Hangover Part III,” which finds the boys returning to Las Vegas after their debaucherous first visit.

The trailer for the movie was just released and, apparently, the past two movies have all lead to this.

So, what is this?

Well, there’s a funeral, the return of Heather Graham, a gross-out scene with Melissa McCarthy and a possible giraffe disaster. Yes, giraffe disaster.

Plus, John Goodman joins the fray as the flick’s big bad guy, while Ken Jeong pops up as a cop … or at least a cop in disguise.

And while there are plenty of shots of Helms, Bradley Cooper and Zach Galifianakis … Justin Bartha is largely MIA, save for one appearance during the 2:00 trailer.

Jessie J‘s new song Silver Lining (Crazy ‘Bout You) will be featured in the film Silver Linings Playbook starring Jennifer Lawrence, Bradley Cooper, and Robert DeNiro.

“Silver Lining (Crazy ‘Bout You)” is not the new single from Jessie J’s forthcoming album, but it will be available for fans to buy as a single track and as part of the Silver Linings Playbook soundtrack album.

The music video is essentially a long trailer for the movie, but it’s really well done! Jessie J is wearing a nude jumpsuit with images, and clips of the film projected all over her body. It’s really well done! From what I could tell, the movie looks pretty cool!

What do you think of the song and the video?
