The 46-year-old actor found worldwide fame through playing Chandler Bing in the hit US television series, which ran from 1994 to 2004.
In February, his co-stars David Schwimmer, Lisa Kudrow, Courteney Cox, Jennifer Aniston and Matt LeBlanc all joined together for a tribute to director James Burrows, but Perry had to miss out due to theatre commitments in London.
When asked if he was sad he missed out on the segment, Perry said, "Not really, because it really wasn't a reunion. It was just six people getting together for a Jim Burrows special. It wasn't really a reunion. And I couldn't do it because I was in London doing my play."
"Because of Netflix, a lot of kids are watching and wondering why I look so old," he laughed.
