Self-described “smart-ass tough chick” Amber Tamblyn is having a ball getting older in Hollywood. She grew up before our eyes, first joining General Hospital at the age of 11 before winning acclaim playing the title role in the television series Joan of Arcadia. But at age 26, she’s a full-blown leading lady and perfectly comfortable showing it off a little. “There’s been a lot of emphasis on sexuality in my life,” she says. “When you’re doing these womanly roles, there are literally contracts about showing ‘side boob’ in a sex scene. I’m not going to take my top off for some random reason, but I’m certainly not against doing a nude scene if it’s for something great. I’m not always going to look like this.”

The LA native, raised in Venice, can currently be seen in the stylish remake of the noir classic Beyond a Reasonable Doubt, also starring Michael Douglas and Jesse Metcalfe. Tamblyn plays assistant DA to Douglas’ character, with whom she formed quite a bond. “He’s a hot silver fox,” says Tamblyn. “We’re both political junkies. He reads every single newspaper on the planet. It was really fun for me. And of course, he’s a brilliant actor.”

Tamblyn will next be seen in Main Street, alongside Orlando Bloom, Colin Firth, Patricia Clarkson and Ellen Burstyn. “It’s the last thing Horton Foote wrote before he died,” she says, “so it’s quite special.” Meanwhile, her other career as an author is getting a recharge with a second book of poetry (out this month), called Bang Ditto. She’ll embark on a crosscountry tour to support it. “It’s the most personal work I’ve ever written. I’m really proud of it,” says Tamblyn. “It’s about being in a fiercely image-based industry.”

We wonder where she could have gotten the idea for that.
