Bob Hope also had a great cameo in Get Smart. He was a waiter. “I’m not the man I used to be. In fact, I never was… except for that one night at the Sands…”
There’s a Pee-Wee Herman movie that features a few seconds of Twisted Sister singing “Burn In Hell”. That scene alone warranted a PG rating for the movie.
In a similar vein, “Calendar Girls” has a section where the elderly women are staying at a fancy hotel, and share poolside space with several members of Anthrax, who do not perform in the movie.

It has to Be Oscar the Grouch in the Muppet Movie
[/QUOTE]Nitpick: That’s actually from The Great Muppet Caper.
“What are you doing here?”
“A very brief cameo.”
“Me too.” 
Most, though, are somewhat longer than cameo - Abraham is the third or fourth front-listed actor, IIRC. Joan Plowright’s role is amusing placement but again longer than a cameo.
I should have remembered Robert Patrick, who like Stone and Bogart was a walk-by. Other than his multi-episode role in Sopranos, Patrick seems to have spent a lot of his career reprising the T-1000 character for joke/shock value.
This is another movie I am sure edited a line between theatrical and video release. In the theater, the Bogart character (a black-and-white figure, dropped in digitally) is announced by the desk sergeant with the line, “Johnson, you’re with the black-and white.” A real howler if you’re paying attention. In video, the line is extended for the stupid as “…with the black and white copy (avatar? figure? something…) of Hum-phrey Bo-gart…” (Viewer: “Ohhhhhhhhh, now I geddit!”)
The movie Brazil has a cute cameo. IIRC it is Robert Deniro. He swoops in like a batman type character to repair a sewage line at an apartment. Then swoops back out.
The whole premise of the movie is the world is basically now one giant disfunctional beuracracy. Deniro is fighting the system.
Odd but interesting movie.
Mel Gibson (back before his career self-destructed) has an uncredited cameo as a body piercer in Father’s Day. It was definitely a “wait, is that…?” moment.
Somebody named Cyril Lord “The Carpet King” on a bat climb in the 1960s “Batman” tv Series. Werner Klemperer’s appearance as Colonel Klink is weird too.
There’s an old 1960s art-house flick called “Petulia” which used to be considered a big deal, but is now mostly forgotten. I happened to watch it once just to see if it stood up to the hype it seemed to get when it came out. The basic plot is a lukewarm soap opera storyline starring George C. Scott and Julie Christie (looking simply smashing!). I didn’t find it anywhere near as interesting as the background – San Francisco in the late 60s.
To my surprise, the movie showed Big Brother & the Holding Co. (with Janis Joplin!) performing a musical number, and the very surreal sight of quintessential humorless adult George C. Scott wandering around a Grateful Dead concert. In fact, the Dead appeared in the background of several scenes acting as a hippie version of a Greek chorus!
John Cleese showed up in a walk-on role in a Tom Baker-era episode of “Doctor Who” as a Louvre museum curator.
There’s Something About Mary
“Brett Favre? What the hell is he doing here?”
“City of Death,” written by Douglas Adams. Dr. Who, Monty Python, and Hitchhiker’s Guide, all in one package. It’s the original Geek Trifecta.
Cate Blanchett played someone’s ex-girlfriend in Shaun of the Dead.
She had a few lines, but it was hard to recognize her under the mask.
The mention of the 1968 movie Petulia reminds me of an interesting cameo in the 1965 movie Darling, which also stars Julie Christie. There’s a character in Darling named Walter Southgate who’s supposed to be a professor. The character isn’t mentioned in the credits. He’s played by Hugo Dyson, who was indeed a retired Oxford professor. Dyson was one of the Inklings (i.e., Tolkien, Lewis, Williams, Barfield, etc.).
The Twisted Sister cameo in Peewee’s Big Adventure?
Authors do seem to like to sneak into these things. Michael Bond appears in Paddington, raising a glass to the bear as he passes by in a taxi.
Colin Dexter is of course the king of this on television, appearing in every episode of Inspector Morse. John le Carré also had a few lines in the recent production of The Night Manager as the elderly gentleman Corky argues with in the restaurant.
Double nitpick: IG was correct - it’s from the original Muppet Movie. The clip is mislabelled.

[/QUOTE]Errr… Triple nitpick : It is NOT from the original Muppet Movie and the clip is not mislabelled The scene IS from The Great Muppet Caper. Why else would Miss Piggy be asking about the Great Baseball Diamond!?
And a special appearance by White Zombie!
Sigourney Weaver makes an appearance as well!
George A Romero is best known as a director of horror films. Stephen King is best known as a writer of horror stories. However Stephen (and wife Tabitha) had cameos in Knightriders, a non-horror Romero film.

Hmm…back to the DVD collection for me…
Gordon Liddy plays an FBI agent toward the end of “Feds” (1988).
Richard Dreyfuss can just barely be seen as an extra on the sidewalk in “The Sentinel” (1977).
Chuck Jones plays a supermarket customer in “Innerspace” (1987).
And a somewhat weird one:
Ralph Bellamy and William Castle both seem to be playing the same impatient person waiting for Rosemary to get out of the phone booth in “Rosemary’s Baby” (1968). You see Castle’s face, but Bellamy only from behind.
Jimmy Buffett plays a “man in black” at the end of Repo Man.
