“This movie is a monster hit already and we’ve just begun to offer it,” LFP sales manager David Diamond said.

Expected to be the biggest selling movie of the year for LFP and X-Play, the company said "Not the Bradys XXX" offers humor, beautiful girls and loads of hot sex, and because it’s a parody of a popular TV show it has become a must-see adventure.

“This movie has a fun, fasted-paced storyline with great sex. It’s the kind of movie you can watch with your girlfriend, wife or both if you’re lucky, but to say this is a couples movie might limit the appeal to those who love hardcore movies because generations of young men have fantasized about what those three sisters look like naked,” director Will Ryder said.

“Wait until you see the three-way with middle brother Peter and his sister’s two girlfriends because it’s amazing and everything that youthful sex should be,” Ryder said. "Damn, you have to be young to fuck like that.”

"Not the Bradys XXX" stars Hillary Scott, Alana Evans, Aurora Snow, Leah Love, Lynn LeMay, Paulina James, Veronique Vega, Jasmine Byrne with Mike Horner, Benjamin Brat, James Deen, Mickey Butders, Tee Reel, Kurt Lockwood, Lu Bricaté and Ron Jeremy as Sam the Butcher.

The title is due in stores Sept. 18.
