Released in 1999, the raunchy teen comedy 'American Pie' became an instant classic with its story of a group of friends on the verge of graduation who make a pact to lose their virginity on prom night. The film kickstarted the careers of several of its cast members (and launched three sequels and a host of direct-to-video spin-offs), and now 14 years later we take a trip back down memory lane to see where they were then, and what they're up to now.

Then: Prior to playing the films' doofy protagonist Jim, Jason Biggs appeared on the daytime soap 'As the World Turns.'

Now: Biggs reunited with his 'American Pie' co-star Mena Suvari in the indie comedy 'Loser' in 2000. In 2001, he made a cameo in 'Jay and Silent Bob Strike Back,' which also featured Seann William Scott and Shannon Elizabeth. Yet another reunion: he currently stars with Natasha Lyonne in the Netflix original series 'Orange is the New Black.'
