Marta Kauffman isn't sure whether the 'Friends' reunion will ever come to fruition

She told 'Entertainment Tonight': "If it happens, we will certainly be involved in it. But I don't know.

"It's complicated. It's very complicated. It's everything. It's a very complicated thing to do."

In November, it was revealed that the show's cast - which included the likes of Jennifer Aniston, Lisa Kudrow, Courteney Cox, Matthew Perry, Matt LeBlanc and David Schwimmer - and the sitcom's creators, Marta and David Crane, were in talks about a possible reunion project.

Kevin Reilly, the chief content officer at HBO Max, revealed there is "interest all round" for a 'Friends' reunion.

He said at the time: "There's interest all the way around, and yet we can't seem to quite get that interest all aligned to push the button on it, so today unfortunately it's still a maybe."

But prior to that statement, David and Marta were adamant they won't revive the comedy.

She said: "We will not be doing a reunion show, we will not be doing a reboot. The show was about that time in life when friends are your family."

And Crane added: "We did the show we wanted to do. We got it right, and we put a bow on it."

Meanwhile, Lisa previously said that a 'Friends' reunion with cast in their forties and fifties would be "sad".

Speaking about a 'Friends'-themed video that had gone viral, she said: "Courteney [Cox] is actually the one who said, 'You see that trailer, oh my god, what do we do?'

"I was like, 'Nothing, that's just a clip, it's just sort of clips from, like, 'Cougar Town'. She wasn't fooled, she was just like 'Wow, how did that go viral?'

"I know, I don't know what to make of it, it's like sort of these weird clips from things that clearly have nothing to do with 'Friends' and it's called a 'Friends' movie."
