Julianne Moore was stunning on the carpet in an ivory Alexander McQueen gown at Tuesday's Still Alice screening in New York, but she couldn't leave the house without her 12-year-old daughter Liv's approval.

"She always has an opinion," Moore joked to ET. "She liked this. She saw me before I left. She's like, 'I like that mama, yeah!'"

We liked it too – and we're not alone. Moore's Still Alice co-stars had some serious Julianne fever.

"I'm so proud of her, I can barely even begin to tell you," Kristen Stewart told ET. "The movie was made so that she can do what she does in it."

"She's just an astonishing woman," Kate Bosworth told ET. "To be able to sit there and watch her perform, she's always brilliant."

The film has already seen some serious awards buzz and is a contender for an Oscar nomination. Julianne already won a Golden Globe for her performance in the film as a mother diagnosed with early onset Alzheimer's disease. During her speech, she gave a very special shout-out to the woman behind the film, Still Alice author Lisa Genova.

"I think I left my body when she named my name," Genova told ET. "I couldn't believe that she had the presence of mind and the generosity of spirit to include me in that speech. I was thrilled!"

Still Alice hits theaters Jan. 16.
