I couldn't remember and why I put "I think", also haven't read complete thread, tho the correct movie is good for others to know. Has the George Lucas Beverly Hills Cop III been mentioned or After Hours (Scorsese) with Cheech & Chong, that movie is a real ride of a film.
The short bald guy in Gallipoli is author Thomas Keneally who wrote the book Schindler's List is based on.
Yeah, De Niro in "Brazil" was an important character, not a cameo. And I'm not sure who missed him - especially given his name was 2nd billed on the poster and featured prominently in the trailer:
FWIW, I have seen this movie many, many times and this is the first I learned that Sting was in it. So I missed it. The Robin Williams part certainly is more than a cameo, even though he is not credited.
Are you just not a big enough fan to recognize him? Sting's role is small but he's onscreen long enough to make it obvious it's him... if you recognize him. Which - as noted - dozens of members of the test audiences did! And that's all they liked about the movie! Williams is credited under a pseudonym. Sting is credited as Sting!
It's possible, especially when I was younger and first saw this, that I may just not have recognized him.
Dunno how young you were, but for those of us late teens/early 20s, we recognized Sting immediately. Unlike Robin Williams in the same film, Sting does qualify as an actual cameo - but not one people missed!
The writer Russell Banks had a cameo as a doctor in the movie version of his novel “The Sweet Hereafter.”
Sadly, that was the only time the three Howard Brothers (Moe, Curly and Shemp) appeared on camera together.
George Harrison as a report in The Rutles - All You Need is Cash BTW, in the area people recognized Michael Palin, but didn't recognize George Harrison.
Not sure if this counts, but: actual Zodiac Killer victim Bryan Hartnell was an extra in the movie Zodiac. He just walked by out of focus in the background of one scene though, so even if you knew what he looked like you wouldn’t know if he wasn’t pointed out.
Not sure if this one has been mentioned, but Danny Lloyd (Danny Torrance in The Shining) appears in the opening scene of Doctor Sleep (the sequel), in the stands of the baseball game.
Peter Sellers in A Day at the Beach. Though it's not hard to spot as he has a whole scene, but the film itself is hard to find.
Noted documentary filmmaker Marty DiBergi playing a meat-head truck driver in the 1979 film The Jerk:
Mad Magazine made a joke of this in an article where they write the ultimate Alfred Hitchcock (parody named "Alfred Hatchplot") movie. In every panel there are multiple appearances of Alfred Hatchplot in every panel. The following Wikipedia page lists all of Hitchcock's cameos: List of Alfred Hitchcock cameo appearances - Wikipedia
