'American Reunion': Behind The Scenes With Jason Biggs, Alyson Hannigan And The Rest Of The Cast (VIDEO)

On April 6, the entire "American Pie" gang returns for the first time in a decade, with the aptly titled "American Reunion." However, just because the cast had worked together several times before didn't mean they weren't apprehensive about making another sequel.

"When we came back, I was nervous," admits Jason Biggs (Jim), in a new behind-the-scenes featurette for the film. Despite his cocky onscreen persona, Seann William Scott (Steve Stifler) echoed similar sentiments:

"I just had a feeling it was going to be special, I thought the chemistry was going to be great. But, I thought, what if something doesn't fit?" said Scott. Luckily, Seann's fears disappeared once everyone showed up on set.

The full clip, which you can watch above, includes the rest of the cast -- Alyson Hannigan, Chris Klein, Mena Suvari, Eugene Levy, Tara Reid, Thomas Ian Nicholas, Eddie Kaye Thomas -- reflecting on the reunion, and gives fans a sneak peak at what to expect from the film.

"American Reunion," directed by Jon Hurwitz and Hayden Schlossberg, hits theaters nationwide April 6.
