Meryl Streep and Amy Adams piled on the pounds while shooting "Julie and Julia."

The "Doubt" co-stars reunited for the forthcoming film - which is about world-famous chef Julia Child and writer Julie Powell, who challenged herself to cook Julia's recipes - and admit the amount of food they had to eat for their roles wasn't good for their waistlines.

Hayden Panettiere is inspired by Meryl Streep. The "Heroes" star insists she wants to be best known for her acting ability and not her private life, citing Meryl - who has been nominated for an Academy Award 15 times - as the person she most admires.

Hayden explained: "I love acting. It's something I respect. It's something that makes me want to be respected for what I do. I'm working toward being a respected actress. Meryl Streep is it for me."
