Some even he didn't recognize.
"It's deep-dish Pie," says the filmmaker, who has had a producing credit on all four features in the series. "It's lovely they paid so much attention."
How do you bake an American Pie sequel? The makers of American Reunion reveal their 10 must-have ingredients:
1. Embarrass Jim (Jason Biggs) early and often.
Hurwitz knew they had to start with a parallel scene of an adult Jim getting caught in the act of masturbating in bed. Only this time he would be discovered by his new family. "Back then, before the Internet made porn prevalent, you could catch it on a scrambled TV channel version, which is what Jim used," Schlossberg says. Now he simply turns on his laptop, although the cheesy background music is the same.
2. Jim encounters a willing - and naked - girl.
"The Nadia webcam scene was big for us," Hurwitz says about the first film's embarrassing hook-up between Jim and the sultry Czech exchange student (Shannon Elizabeth) that goes viral. "It's probably the first comedy sex scene to use the Internet in a major way," observes Schlossberg. The incident is echoed in Reunion when Jim drives home the drunk girl he once babysat. She strips off her top and tries to seduce him - in a Mini Cooper.
3. Oz the jock (Chris Klein) gets down.
In the first Pie, Oz joined a jazz choir to serenade would-be conquest Heather (Mena Suvari). "Hearing Oz singing had an endearing influence on us," Hurwitz says. In Reunion, the now-celebrity TV sportscaster is put through his musical paces doing B-boy moves on a dance-competition reality show.
4. Got MILF?
MILF guy No. 1 (Justin Isfield) and No. 2 (John Cho) are back after idolizing Stifler's mom (Jennifer Coolidge) in the first Pie. This time, there is a new MILF in town, a surprise cameo by an actress who broke out in a 1983 youth comedy.
5. Stifler's steady-cam entrance
In the first film, Stifler (Seann William Scott) walks through his house party with a camera while lobbing insults and suggestive wisecracks at guests. He makes a similar entrance in Reunion at work but with bittersweet results. "It shows he is the same guy, but the world has changed around him," Hurwitz says.
6. It's the same old song.
New Zealand pop star Bic Runga's tender Sway played during the post-prom coupling montage in the first film. This time, it's heard when Oz and Heather connect at the reunion party.
7. The intro to Stifler's mom
Seems as if Stifler's mom has been in her lair for the past 13 years, waiting for a hot-to-trot visitor to stumble in. When he arrives, the same brassy melody blares. "It's martini music," Schlossberg says.
8. Something's cooking.
The first film found Jim engaged in coitus with his mother's baked apple dessert. Now he is in another awkward spot in the kitchen and uses a clear pot lid as a makeshift fig leaf. "At our first test screening, it played like a rock concert," Hurwitz says.
9. Stifler's gross-out moments
Scott has drunk tainted beer, been sprayed by someone relieving himself and eaten a questionable truffle. What's left? Defecating in a picnic cooler to avenge wrongdoers.
10. Those awkward father-son talks
The highlight of any Pie film is when Jim's dad, once more played with clueless insouciance by Eugene Levy, over-counsels his son about the birds and the bees. Now the tables are turned as Jim fills in his widower dad on matters of the heart.
