Both mom and dad were dead-set against letting Willa Holland pursue acting, but it’s hard to argue when two legendary directors insist otherwise.

“I was playing over at Steven Spielberg’s house” — next door to stepfather Brian De Palma’s place in the Hamptons — “and he was filming little wedding scenes and doing homevideos,” she says.

When her parents came to pick her up, Spielberg insisted, “You’ve got to put her in front of a camera.” De Palma was for it, too.

So Holland took their opinions to heart, starting off as a teen model, before graduating to a steady acting gig on “The OC.” The show’s producers loved working with her so much, they invited her to do three episodes on “Gossip Girl” this fall.

The 17-year-old agreed, though she insists the bigscreen is her focus going forward. Holland played a teen wannabe-actress wasting away on the fringes of Hollywood in “Garden Party” and co-stars in two indies at the Toronto Film Fest last month: “Middle of Nowhere” and “Genova.” Next up is doomsday fantasy “Legion.”
