Jason Biggs Hosts First American Pie Reunion in 13 Years (Exclusive)

Jason Biggs is reuniting with his American Pie costars for the first time in more than a decade.

Biggs will reunite with cast members from the 1999 classic movie and its sequels on his and his wife Jenny Mollen’s TBS show, Dinner and a Movie. Joining the duo for a special reunion to spill some of the American Pie tea are fellow castmates Alyson Hannigan (who played Michelle in the franchise), Mena Suvari (Heather), Chris Klein (Oz) and Shannon Elizabeth (Nadia).  

The event comes 13 years after the actors last got together in 2012’s American Pie Reunion — the film franchise’s fourth big screen installment — to catch up 13 years after their high school graduation.

In an exclusive interview with PEOPLE, Biggs, 47, says he and his wife began having conversations about an American Pie reunion when they “first signed on” to Dinner and a Movie.

“We knew it would be important to get some of my friends from the movie to come back on, if we could, and Mena stepped right up, which I love,” he says. “You know, Mena and I have worked together on other things, and she knows my wife as well a little bit, and so it was really great when she said yes. I was so, so happy. And Alyson came on with her as well, and then we had Shannon Elizabeth and Chris Klein.”

The end result, he adds, “exceeded my expectations.”

“Because I knew we’d get nostalgic and take a trip down memory lane, but I mean, Mena brought a bag of memorabilia, like, things that I was tripping out over,” he adds.

That bag included scripts and notes made during filming — along with some other fun bits of nostalgia.

Speaking to PEOPLE, 46-year-old Suvari said she just happened to be organizing some old things when she got the call from Biggs about a potential reunion.

“I just happened to have gotten new bins from The Container Store to house all of my stuff,” she says, adding that she has kept “every script that I work on.”

“Now everything’s online, but I have all of, like, the, you know, the tangible stuff,” she says. “And so, ironically, I was doing that, and then knew that I was going be on the show with everyone, and I remembered that I had come across all that stuff.”

The “stuff” included early scripts from before the film changed its name to American Pie. As Biggs explains, the film was first referred to as “Untitled Teenage Sex Comedy That Studios Will Probably Hate, but We Think You Will Love, That Can be Made for Under $10 Million,” before it’s name was changed to “East Grand Rapids High,” then “East Great Falls High,” then “Great Falls”, then “American,” and finally, “American Pie.”

Other souvenirs from her time on set, Suvari says, include “the cover sheets with an address and a time of where we needed to be — I even had drawn, like, the intersections of the streets, because we didn’t have [navigation] back then.”

Says Suvari of the reunion: “For me, it’s really beautiful, it’s really special … American Pie has always been such a huge gift for me, and it’s just really special to have that connection to a film. I mean, it’s something that I feel like a lot of people in this industry would be so grateful to have, and for it to continue to have this legacy is just… It’s really the greatest gift.”

Biggs concurs, adding, “I wish we saw more of each other, you know? I wish we leaned on each other even more. But, you know, that’s the beautiful thing about these relationships that I have with this cast, is when you see them again, even if it is a huge stretch of time since you last saw them, it’s immediately so easy.”

He continues: “You know, we’ve gone on in our lives, and we’ve lived 27 years, we’ve grown up, we have kids, we have lives, and we carry this American Pie thing with us. … the success of that movie is something that is so special and unique, and we are the only ones that have it. In that sense, we are family, and it’s like growing up in the same household, you know? We’re the only ones that can talk about what it was like to grow up with their mom and dad in that house, you know?”

The episode of Dinner and a Movie showcasing American Pie and a special cast reunion premieres Saturday, Aug. 23, at 8 p.m. ET/PT on TBS.
