Julianne Moore On Her 'Pretty Big Deal' Oscar Win

— -- Sunday night was finally Julianne Moore’s time to shine.

The 54-year-old actress took home the Oscar for “Best Actress” for her portrayal of an Alzheimer’s patient in “Still Alice.”

Despite being nominated four times before, this was Moore’s first win.

"I honest to God can’t believe it. It’s crazy,” she told George Stephanopoulos backstage after her acceptance speech.

Though oddsmakers predicted Moore was a lock for the win, she said she was shocked.

“It’s still a surprise,” she confessed. “It’s still a pretty big deal.”

Moore beat out competition from Marion Cotillard, Felicity Jones, Rosamund Pike and Reese Witherspoon, taking the stage to crack a joke before heading into her thank yous.

“I read an article that said that winning an Oscar could lead to living five years longer,” she joked. “If that’s true, I’d really like to thank the Academy because my husband is younger than me."
