Model turned actress Devon Aoki was a pillar of red in a Zac Posen gown at the New York premiere of her new movie, "Rosencrantz and Guildenstern Are Undead." The quirky film puts her opposite Jake (son of Dustin) Hoffman
in the story of a Hamlet production made by vampires.

"It was one of the best experiences of my film career," Aoki told StyleList at the premiere. She was flanked by her equally beautiful aspiring-actress sister, Elliot Stuart Hunter, and singer Sean Lennon, who performed a private concert at the after-party.

"I'm always learning, especially on set," Aoki said of jumping from fashion to acting. "I've been modeling since I was 14, so it's something that I know and understand quite well. And the acting stuff I've been doing since 2003, and I have to learn from all the people I can. Every time I do a film, I learn a little bit more. You get more invested and realize it's a very serious undertaking."

"Rosencrantz and Guildenstern Are Undead" is a surprisingly charming comedy featuring star turns by familiar faces including Ralph "Karate Kid" Macchio as an Italian tough guy and "Law & Order" star Jeremy Sisto as a New York cop. Veteran actor John Ventimiglia -- you might remember him as the restaurateur from "The Sopranos" -- practically steals the show as the villainous bloodsucker Horatio. (It is true that some of the plot points do not stand up to close examination -- but this is a vampire comedy, so what do you want?)

Aoki admitted that movie people had a lot of preconceptions about her since she had achieved fame as a model.

"Especially when you haven't done anything in film and you're not a seasoned actor," she said. "It takes time, and every film I do is an eye-opening experience. You learn from other actors, and I do love doing it, so it's fun."

Jake Hoffman ambled by long enough to make a joke about his father, who had been photographed that day locking lips with Jason Bateman at a Los Angeles Lakers game as a lark for the Kiss Cam. So, are the two men dating?

"Yes," the younger Hoffman said with a smirk. "It's a good thing!"
