Chevy Chase was "hurt" by his exclusion from Saturday Night Live's 50th anniversary celebrations.
The 82-year-old star was an original cast member on the long-running sketch comedy series and has expressed disappointment at his lack of involvement in the special anniversary episode that aired in February and saw a host of SNL alumni return.
Speaking in the upcoming documentary I'm Chevy Chase and You're Not, Chevy said: "Well, it was kind of upsetting actually.
"This is probably the first time I'm saying it. But I expected that I would've been on the stage too with all of the other actors. When Garrett (Morris) and Laraine (Newman) went on stage there, I was curious as to why I didn't. No one asked me to. Why was I left aside?"
Chase was also baffled that Bill Murray featured as anchor of SNL's Weekend Update segment - a part of the show that he had created.
The National Lampoon's Christmas Vacation star said: "Why was Bill Murray there and why was I not? I don't have an answer for that."
Chevy revealed that he contacted SNL creator Lorne Michaels about the "bad mistake" that was his absence.
He said: "I did bring it up once in a text to Lorne and then took it back.
"I said, 'Okay, I take it back, silly.' But it's not that silly. Somebody's made a bad mistake there. I don't know who it was, but somebody made a mistake. They should've had me on that stage. It hurt."
Chase left SNL in 1976 and claimed in a previous interview that the quality of the show declined after his departure.
He told the Washington Post newspaper in 2018: "I'd have to say, that after the first two years, it went downhill. Why am I saying that? Because I was in it? I guess.
"That's a horrible thing to say. But certainly I never had more fun. I really loved it and enjoyed it. I didn't see the same fun thing happening to the cast the next year."
