Matthew Perry is concerned a 'Friends' reunion could "ruin" the sitcom.
The 46-year-old actor portrayed Chandler Bing for 10 years in the sitcom, which aired its finale in 2004, but he has reservations about the programme ever coming back because the successful 10 series ended "so well".
He said: "That's the concern about doing a reunion show or a movie because it ended so well and you don't want to ruin that.
"Everybody always asks about a reunion and there's been no real talk of it."
Despite his concerns, Matthew admits he would be up for reprising his role if producers decided to create an 11th series or put 'Friends' onto the big screen.
Speaking on ITV's 'This Morning', he added: "It was such a great job. We all loved each other so much and we all had such a great time that subsequent jobs have been harder to do than that one.
"So yeah, I guess it would be nice to go back and do more because it was just so much fun."
Matthew's 'Friends' co-star David Schwimmer - who portrayed Ross Gellar on the popular sitcom - recently said he was "sure" a full reunion would happen one day.
He said: "I think it's lovely [the show is still popular]. I love that people are that into the show and I would love to see the six of us together and I'm sure one day we will be."
The pair appeared alongside Jennifer Aniston, Courteney Cox, Matt LeBlanc and Lisa Kudrow in the sitcom series.
