AFAIK, Spielberg isn't in the movie. He's in the music video, though it'd be hard to miss him, as Lauper asks for him right before we see him. Did you mean Spielberg's "Gremlins" cameo?
Noel Neill and Kirk Alyn (1940s-50s Lois Lane and Superman respectively) in brief train scene in 1978's Superman. Later extended version showed them to actually be Lois Lane's parents.
Just watched the jail scene - no sign of Spielberg. Also can find no photos of him in "Goonies" or any reference to him doing a "Goonies" cameo. If you can find evidence of Spielberg's "Goonies" cameo, let's see it!
Not really a cameo, but I had no idea Will Ferrell was in the truly awful Tim Meadow's vehicle THE LADIES MAN. In a moment of weakness I watched this on Prime over the weekend for the first (and last) time, enabling me to see this surreal bit of nonsense.
Bowie is credited in the opening credits so I wouldn't consider it a cameo. Maybe more of a featured bit role.
Dwight Schultz, Murdock on the TV series "The A-Team", made a cameo in the big screen version (he was the doctor with the glasses)....
Dwight Schultz's other famous role, Reginald Barclay from "Star Trek - The Next Generation", also made a cameo in the feature version of "The A-Team". Ok, the theme music from the TV version of "The A-Team" also made a cameo....
Walter Matthau in a cameo as a drunk in Earthquake I doubt many missed it but it was an odd moment that took me out of the film at the time. I kept expecting him to show up again.
I was just 7 when I saw "Earthquake" in 1974, but I knew who Matthau was. I remember thinking it was Matthau but thinking it couldn't actually be Matthau because it was such a small part! The name escapes me, but there was also another character actor back in the 70s who looked a lot like Matthau and who would play roles like that...
Two things: 1.Wasn’t the wrecking crew in quite a few films as musicians? 2. I thought I read there were many big celebrities that wanted to play dead bodies in the NCIS and CSI series
