Jennifer Aniston opened up about filming “Friends: The Reunion.”

She revealed feeling emotional while on set.

She told The Hollyword Reporter: “it just took me by surprise because it was like, 'Hi, past, remember me?’”

She added, “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.”

Aniston admitted that it was because of director Ben Winston that she agreed to do the reunion.

She noted, “We were all like, 'I don’t know if we were just seduced by his talent or his charm or a combination of all of it.’"

While the experiences were not all good, she said she still had "so much fun” with her cast members.

Aniston also feels extremely grateful for the opportunity.

She said, “I didn’t know what was coming, and that’s been nothing but blessed.”
