He may be a big-screen star, but it's Zac Efron's Web video that has people talking this week.

The cast of his upcoming feature, 17 Again, teamed up with a few celebrity pals recently to shoot a wacky video short for Efron's funnyordie.com debut, set to air Wednesday.

Brody Jenner, Joel Madden, Queen Latifah, Justin Long, Nicole Richie, Vanessa Hudgens, Carmen Electra, Brittany Snow and Lance Bass all take part in a "pool party from hell," according to 17 Again producer Adam Shankman who co-directed the FOD video.

"We wanted to do something goofy including cast members, but it wasn't a direct promotion," Shankman tells PEOPLE of the digital short. "It's very, very silly. It's Zac Efron's nightmare pool party where Tom Lennon and Nicole Sullivan, who are also in 17 Again play his white trash uncle and aunt and come and just humiliate him in front of a hip, young Hollywood crowd and they offend literally everybody in sight."

Some highlights? "We have Brody Jenner talking about the AIG thing," he says, adding, "Queen Latifah is deejay trying to sell her scabies medicine."

Check back Wednesday for the clip and more behind-the-scenes scoop from Shankman!
