The three guys who have never made a feature, either together or apart, bring a similar blend of innocence and anarchy to Hot Rod, an 82-minute joyride that appears to have been a blast for the trio to make. Samberg is more than game for occasionally putting on a fake mustache as the aspiring Evel Knievel–esque daredevil Rod Kimble, while Taccone plays his George Michael–enthusiast half-brother Kevin, and Schaffer took his usual spot behind the camera to direct.

The film's screenplay is credited to Team America screenwriter Pam Brady, who Schaffer considers a kindred spirit and whose script he describes as "weird and surreal and absurd and quirky in a way that feels honest to us." Still, Hot Rod is decidedly a Lonely Island affair, complete with punchdancing (a sequence that imagines the boxer played by Sylvester Stallone in Rocky directed by Stallone circa Staying Alive) and a two-minute riff on the phrase "cool beans" that after 30 seconds shifts from a funny non sequitur into a masterpiece of Dadaist art.

The Lonely Island also features a growing company of comic partners in the film, including Samberg's SNL castmates Bill Hader and Chris Parnell, with whom Samberg scored his first major success, the Narnia and cupcake-inspired rap "Lazy Sunday." Samberg also cast his NYU roommate Chester Tam, whose unexpected (and wholly unwarranted) dance moves get some of the film's biggest laughs.

Schaffer says the group has ideas about a next film, and, although Hot Rod is bound to open up some new opportunities, success won't change the Lonely Island's commitment to each other.

"Everything we do, we're still learning as we're doing it, and our style is growing and becoming a little more concrete, I think," Samberg says. "And we have each other. When one of us turns to the other two and goes, 'Is this funny?' and they both say yes, that's really my bottom line of whether or not I believe it's true."
