The Rachel Green actor said the unnamed star acted like they were “too above” appearing on the hit US sitcom, and felt like they “shit on” their friendly set environment.
Speaking to US radio host Howard Stern, Jennifer revealed that the male actor did actually end up “apologising about their behaviour years later”.
“He just said, ‘I was so nervous, to be honest, that I wasn’t on my best behaviour’,” she said.
“It was as if they were just too ‘above’ this, to be on a sitcom,” she continued. “And I remember when we were doing a network run-through, the network and the producers would just laugh. And this person would be like, ‘Listen to them, just laughing at their own jokes. So stupid, not even funny’.
“It was just like, ‘What are you doing here? Your attitude, this is not what we’re all about. This is a wonderful, warm place to be, and you’re coming into our home and just shit on it.’”
Jennifer shot down Howard Stern’s guess that the actor in question was Tom Selleck, who played Dr. Richard Burke from 1996 to 2000, and also insisted it wasn’t Sean Penn, who appeared in season eight.
A season one guest star previously issued a public apology to the Friends cast earlier this year for behaving like “a dick”.
Fisher Stevens – who played a psychiatrist called Roger, a love interest of Phoebe Buffay’s in The One With The Boobies – admitted he was “kind of an asshole” while filming the show.
Fisher told PeopleTV’s Couch Surfing: “At that moment in my career, I had never done a sitcom before. I had never heard of Friends because it was just the beginning of the show and I didn’t watch TV at the time much.
“I was kind of an asshole, I have to admit. ‘What do you mean? So I have to re-learn lines that you’ve written that are worse than what you’d originally written?’ Yeah, I was a dick.”
Fisher said he had “rarely seen” any of the Friends cast since, but said: “I’m sure if you asked them about me, they would go, ‘What a New York snob’.”
He added: “Yeah, I’m sorry, guys. I’m sorry I was a dick to you all. I apologise. I was bad, I was wrong.”
