The marketing machine behind the upcoming ensemble sex comedy "A Good Old Fashioned Orgy" has now kicked into full gear as just after a batch of clips and pics from the film hit late last week, your Monday is getting kicked off with a red band trailer for the flick. And you know what? It's pretty amusing.

Led by the omnipresent Jason Sudeikis, the film boats a pretty simple premise: as a send off to the cottage where a group of friends have summered for years, a final blowout orgy is planned. Even though the film is lined up to be a cameo fest, it seems everyone is making the most of their time. Will Forte and Lucy Punch as the newlyweds who are pissed at their friends for just now deciding to do an orgy are a highlight, while David Koechner also appears with a strange request (and look, there's Martin Starr!). We caught the film earlier this spring at the Tribeca Film Festival, calling it a worthy throwback to films like "Animal House" and "Stripes," and at the very least it looks like it will put a solid cap on a long summer of foul mouthed comedies.

Tyler Labine, Leslie Bibb, Lake Bell, Michelle Borth, Nick Kroll and Lindsay Sloane round out the cast for the film that will make Labor Day sexier when it opens on September 2nd. Check out the trailer below.
