"Oh, nothing will be different," Biel told me last night at the special screening of her new movie, Hitchcock, at the Academy of Motion Picture Arts and Sciences in Beverly Hills.
"It's all about family and we don't mess with the grandmothers," she said. "They do all the cooking."
Biel, who loves to cook, said she won't even dare to try preparing a side dish. "You're not even allowed in the kitchen," she said. "I'm not allowed to do any of the cooking. I'm just going with tradition."
And it was some old traditional accessories that helped Biel play real-life actress Vera Miles in Hitchcock (in theaters on Friday). The movie, from director Sacha Gervasi, tells the story of the making of Alfred Hitchcock's Psycho in 1959. Anthony Hopkins stars as the legendary director with Helen Mirren as his wife of 54 years, Alma Reville. Scarlett Johansson plays Janet Leigh.
"I think most of all, it's the undergarments," Biel said of her look. "They really change the shape of your body. And it's not sexy, either. It's like girdles, old-school girdles. It's not cute."
But, she said, the wardrobe was "feminine and beautiful."
"It changes the way you stand, the way you walk and they way you hold yourself," Biel said. "Who you are visually and viscerally is different."
Also at the screening, which included a reception catered by legendary Hollywood restaurant Musso & Frank Grill, were Mirren, Toni Collette (she plays Hitchcock's secretary in the film), Leigh's daughter Jamie Lee Curtis and Jillian Rose Reed of MTV's Awkward.
