The Ant-Man star joined Friends in its penultimate series as Mike Hannigan, a new love interest for Phoebe Buffay, who Lisa Kudrowās character eventually went on to marry.
Because of his characterās connection to the core six, Paul was part of the Emmy-winning sitcomās final episode back in 2004, which he has now admitted he had mixed feelings about.
Asked about his time on Friends during a recent interview with the Heart breakfast show, Paul said: āIt was really fun, and they were great! The whole thing was a bit surreal. I must say.ā
He continued: āI never knew that I was going to be in as many [episodes] as I was. But it also felt strange.
āI mean, I was in that last episode. And I just thought, āI shouldnāt be here... Iām getting, like, a front row seat to things Iām not supposed to seeā.ā
āThey were all crying,ā he added. āIt was all emotional. I was just like, āwoahā.
āI meanā¦ I felt very privileged, but I also was like, I just donāt want to sit back here and get in that way.ā
Paul is currently in full promo mode for the new Marvel film Ant-Man And The Wasp: Quantumania, which marks his third outing at the helm of the Ant-Man franchise.
Last week saw Paul going viral when he was prank-called live on Radio 1 by a very famous friend, as well as giving two Australian reporters a masterclass in the delicate art of the Hollywood wink.
