'American Pie' cast: Where are they now?

2 of 12: Seann William Scott once starred in Aerosmith's 'Hole in My Soul' music video in 1997 and later went on to play Steve Stifler in all three major 'American Pie' films. He also appeared in the comedy movies 'Old School' in 2003, 'The Dukes of Hazzard' in 2005 and Kevin Smith's 2010 flick 'Cop Out,' which also starred Bruce Willis. He also appeared in the 2011 film 'Goon' with 'American Pie' co-star Eugene Levy as well as Jay Baruchel and Liev Schreiber.

In March 2011, he entered a treatment facility for 'health and personal issues,' his spokesperson said. Also that month, it was reported that he will reprise his 'American Pie' role in a fourth big-screen film that would reunite the original cast members.

Scott left the Malibu clinic in April of that year after completing his treatment program.
