Welsh actor Michael Sheen took on the infamous role of Stifler's Mom opposite Sharon Stone as Jim's Dad in a gender-swapping live-read of teen movie American Pie in Los Angeles. The Frost/Nixon star and the Basic Instinct actress were among the cast for a live performance of the film on Thursday night (16Jan14) as part of director Jason Reitman's regular series of star-studded read-throughs at the Los Angeles County Museum of Art. The American Pie show featured the actors swapping gender roles, with Sheen taking on the feisty femme fatale played by Jennifer Coolidge in the original film and Shannon Elizabeth's part of Nadia. Stone played the role of Jim's Dad, originally played by Eugene Levy, Twilight star Anna Kendrick tackled Seann William Scott's Stifler, and Spider-Man 3 actor Topher Grace channelled Tara Reid to play Vicky. Other stars in the production included Olivia Wilde as Kevin, Krysten Ritter as Finch, John Cho as Heather, and Ari Graynor as Jim. Sheen shared his news with fans following the performance in a series of posts on Twitter.com, writing, "Tried my best to get inside Shannon Elizabeth and Jennifer Coolidge tonight. A gender-reversed reading of American Pie at LACMA. Huge fun!... I was of course playing Nadia and Stifler's Mom! Sitting between Sharon Stone as Jim's Dad and Anna Kendrick as Stifler. Marvelous!!!"
