Just the one I was going to mention.
Got called away before I could edit. And John Travolta playing himself playing Goldmember.
Peter Falk as Peter Falk the angel in Wings of Desire (Der Himmel über Berlin). And probably Nick Cave (and the other Bad Seeds) as themselves.
I like when Merv Griffin shows up in The Man With Two Brains, and rants about his inability to get away with lurking due to his celebrity.
In the “Columbo” ep Uneasy Lies the Crown, Columbo walks in on a card game, and three of the players are Ron Cey, Nancy Walker, and Dick Sargent.
Almost forgot, The Beatles first make an appearance in Strange Tales #130, and are later featured in at least a dozen titles. (Although I’m not sure you can count the comic adaptation of Yellow Submarine)
Alice Cooper as himself in Dark Shadows.
Bob Keeshan (Captain Kangaroo) appears as himself in The Stupids
When Paul Simon was the guest singer on an episode of SNL, Senator Paul Simon showed up.
It was hilarious
The fourth one, the one doing all of the impressions, was John Roarke, who was a performer on the late-night sketch show Fridays.
In the circus movie “The Greatest Show on Earth” there is a scene panning the crowd. Bob Hope and Bing Crosby are sitting in the front row eating popcorn
It may be easier to say who hasn’t voiced themselves on The Simpsons.
The one person I can think of who was asked but turned the show down: Bruce Springsteen - and, in fact, “his” part was rewritten for Sting.
In Airplane a soldier in the psych ward believes he is Ethel Merman, played by Ethel Merman.
A while ago I started a thread asking a similar question. I was specifically looking for examples of celebrities playing an unflattering version of them selves for laughs. I was also trying to figure out if the Larry Sanders Show is what made this into a popular plot device.
This would totally explain Seinfeld…
Preceded by Garry Shandling’s own It’s Garry Shandling’s Show, which is more likely to have launched the genre in a significant way.
Even weirder because it seems to have been the entire point…
Dave Sim in Cerebus the Aardvark. Somewhere between issues 187 and 190 - we’re talking 15 years of comics - the lead character Cerebus begins conversing with an all-knowing entity named ‘Dave’ who reveals his possible futures and pasts.
It’s. Truly. Weird.
And in interviews Sim said that he’d had the entire run of Cerebus laid out in his mind up until the point where ‘Dave’ introduces himself to Cerebus. The entire run. From that point on it just got weirder and less coherent. Hemingway appeared. F. Scott Fitzgerald appeared. The Three Stooges appeared. Cerebus ended up an award winning hockey goalie.
As I said. Weird.
In the 1940s, comic book creators were definitely NOT famous, but when Bob Kane was the lead artist on Batman, Bruce Wayne bore a striking resemblance to Bob Kane.
I WAS going to mention Regis Philbin appearing as himself in 1992’s Night and the City, but at the last minute, I noticed that the thread title calls for our favorite cameos.
So I have to go with George Raft flipping his silver dollar while he watched the brawl in Casino Royale (the good one; not that monstrosity where everyone acts as though Bond deserves to be taken seriously).
My nominations are David Duchovny appearing (twice IIRC) on The Larry Sanders Show followed by Garry Shandling appearing on The X-Files. I strongly recommend you go look them up and watch them. In that order.
Funniest line ever to appear on The X-Files. “Mostly?!”
Henry Mancini applauding from the cheap seats after Pink Panther conducts the Pink Panther Theme.
The first thing that popped in my head when reading this was Rick Springfield in Californication. Hilarious.
