Meryl Streep is my choice for Best Actress for "Julie & Julia"
Not being an American, I never heard of Julia Child before I saw the film. Still, I was instantly enchanted by her - and all thanks to Streep. Besides I later checked out the video of real Julia Child and was could see that Streep did an ingenious portrayal.
Streep's Julia is an extremely lovable character, despite her rather plain features, unwomanly tallness and shrill voice. She's kind, sweet, smart, a bit naive and confident at the same time, charming everyone around her. Her love for cooking proves completely infectious and the film itself is nothing short of "delicious" - all thanks to Julia/Meryl.
