Earlier this year, Aniston and her 'Friends' co-stars all got together in front of an audience for the first time since the last season of the show. The reunion was a huge success, but clearly quite an emotional process for everyone involved.

Aniston, in particular, had a difficult time dipping back into the space of Rachel Green, the character she left behind all those years ago. Speaking to The Hollywood Reporter, she went into detail about 'Friends: The Reunion'.

"I think we were just so naïve walking into it, thinking, 'How fun is this going to be? They’re putting the sets back together, exactly as they were.' Then you get there and it’s like, 'Oh right, I hadn’t thought about what was going on the last time I was actually here.'"

"It just took me by surprise because it was like, 'Hi, past, remember me? Remember how that sucked? You thought everything was in front of you and life was going to be just gorgeous and then you went through maybe the hardest time in your life?'"

The 'Morning Show' star found the reunion so emotional that she even had to leave the set a few times to gather herself.

"It was all very jarring and, of course, you’ve got cameras everywhere and I’m already a little emotionally accessible, I guess you could say, so I had to walk out at certain points. I don’t know how they cut around it."

Speaking about how her profile has changed over the years, Aniston said she started out her career as "the girl next door, the damsel in distress, the broken-hearted - your traditional rom-com themes". She added, "At a certain point, it was like, 'Can’t we do something else?'"

Aniston stated the one director she wants to work with in the future would be Wes Anderson. "There are still certain directors I’d love to work with, ones who have their pick of who they like, and sometimes I want to go, 'I’d love to be part of that club.'"
