Universal has been trickling out teasers for “American Reunion” for about a month now, but we finally have an official trailer that features the original cast. All the original members of Jason Biggs’ motley crew are set to return for more immature hijinks and masturbation jokes.

Writer-directors Jon Hurwitz and Hayden Schlossberg (Harold & Kumar) will helm. “American Reunion” opens April 6th, 2012.

Here’s the official synopsis for “American Reunion”:
In the comedy American Reunion, all the American Pie characters we met a little more than a decade ago are returning to East Great Falls for their high-school reunion. In one long-overdue weekend, they will discover what has changed, who hasn’t and that time and distance can’t break the bonds of friendship. It was summer 1999 when four small-town Michigan boys began a quest to lose their virginity. In the years that have passed, Jim and Michelle married while Kevin and Vicky said goodbye. Oz and Heather grew apart, but Finch still longs for Stifler’s mom. Now these lifelong friends have come home as adults to reminisce about—and get inspired by—the hormonal teens who launched a comedy legend.
