As previously reported, the Odd Couple actor won't be in town when his former costars — Jennifer Aniston, Courteney Cox, Lisa Kudrow, David Schwimmer and Matt LeBlanc — film a two-hour special for director-producer James Burrows next month.
"It's not the reunion everyone is hoping for. They are celebrating Jim Burrows, who was a director of Friends," Perry, 46, said during the BBC show, via the Daily Mail.
"The other five are going to be on this special and I am going to introduce them from London," he continued. "I'm doing the play here so I can't be there." (Perry's publicist, Lisa Kasteler, told Us Weekly on Thursday that the actor will be rehearsing for his London play The End of Longing.)
Friends ran for 10 seasons on NBC, from 1994 to 2004, and has become one of the most beloved shows of all time. "I knew it would be a success and that we had something special, but I didn’t know the giant hit it would become," Perry said on Friday.
The series became so popular that the cast earned $1 million per episode in the final season — much to the dismay of cocreator Marta Kauffman.
"A million dollars an episode is kinda ridiculous. Let's be honest, that's a lot of money," she said at the TCA Summer Press Tour in July 2015. "There's something unrealistic about it. Not everybody is going to get a million dollars an episode."
