The Ant-Man and the Wasp: Quantumania actor shared his perspective on joining the legendary sitcom as Phoebe's (Lisa Kudrow) husband Mike Hannigan in the penultimate season. "It was really fun, and they were great! The whole thing was a bit surreal, I must say," the 53-year-old actor said on the Heart breakfast radio show. "I never knew that I was going to be in as many [episodes] as I was. But it also felt strange."

While his costars were emotional at the end, Rudd said he felt like it might have been more appropriate if he took a backseat. "I was in that last episode. And I just thought, 'I shouldn't be here… I'm getting, like, a front-row seat to things I'm not supposed to see,'" Rudd recalled. "They were all crying. It was all emotional. I was just like, Whoa." He added, "I felt very privileged, but I also was like, I just don't want to sit back here and get in the way."
