Eliza Dushku has had “a lot of cool experiences and opportunities” since breaking into show business as a preteen. (Hard to believe the “Buffy the Vampire Slayer” actress was barely 14 when she played Arnold Schwarzenegger’s daughter in “True Lies.”) She’s traveled all over the world and been to some hot Hollywood parties, but just as gratifying, Dushku says, is the fund-raising work she’s done in recent years for Camp Hale. “From a family perspective, and as something I’m really passionate about, this means a lot to me,” says Dushku, who’ll turn 33 in December. The Watertown native will be rewarded for her efforts when the American Camp Association honors her at its Camp Champions Celebration at Fenway Park Friday night. (Click here for tickets.) Camp Hale, located on Squam Lake in the White Mountains, has been an oasis for generations of boys from Boston’s urban neighborhoods. Dushku’s father went to camp there, as did all of her brothers. But girls weren’t allowed. Until last summer, that is. Dushku helped raise money to create an all-girls session at Camp Hale, and she was there to enjoy it. “It was really special to be on the lake where I was used to seeing little boys in canoes, but instead I saw little pigtails in the canoe,” she said. “It was really wonderful and I want it to continue.” Though she’s lived in Los Angeles for 15 years, Dushku has been back in Boston a lot lately to spend time with her stepfather, James Coleman, who died in October. She also just wrapped an independent film in New York called “Jane Wants a Boyfriend,” which was more character-driven than some of her high-profile TV work. “I didn’t have a stunt double and I didn’t wear leather pants,” she said.
