Behind the scenes:
Aniston says of playing a mourner suffering chronic pain, "I actually loved her, but the movie has a beautiful way of unfolding itself without giving the story away and allowing the audience to go with the journey as it's being told."

BEST DRESSED HOPEFUL

Why we love Jennifer's fashion:
"Just when you think you know the reigning queen of LBD's, you find out she has tricks up her sleeves (yes, like that time she wore a F-L-O-R-A-L dress!).

What Jennifer says about her style:
"Of course I'm loyal to my fashion go-to. I love a little black dress," she said. "It's a great wonderful, fun, easy piece of clothing to have. I have a couple!"

PLUS-ONE TO WATCH

Outstanding performance by a female actor in a leading role nominee Jennifer Aniston.

Justin Theroux

Relationship status:
Jen's been blinding us with her 8-carat cock since her fiance screenwriter/actor Justin Theroux popped the question back in 2012.

Look out for:
A selfie-less trip down the red carpet this power couple doesn't show off their romance on social media (it's okay; we'll just settle for the inevitable paparazzi shot of them gazing lovingly into each others eyes). Theroux celebrated his 41st birthday with the best present ever: America's undisputed sweetheart accepted his proposal, which came just over a year after they were first spotted together in May of 2011.

Her hot and sweaty introduction to Theroux:
"I remember thinking, 'Isn't he hot?' But he was actually really quiet. I later came to find out that he was just exhausted because he had been writing nonstop, like a little hamster on a wheel. This was his on night off, and he had no personality, but he was very sweet and very overdressed. I was like, 'You must be really shvitzing up a storm in those jeans and combat boots," recalled Aniston.
