I just rented Clockwork Orange* done by the late Mr. Kubrick, and when Malcolm McDowell’s character was in the record store, just before her shagged the two birds, the album cover in plain view at the counter was 2001, A Space Oddessy, a previous release of said director.
Do you recall other movies where a blatant or subtle reference was made to a previous movie? (Sequels do not qualify).
Characters and lines from Clerks (his first movie) are referenced in the next three movies-Mallrats,Chasing Amy and Dogma. Too many examples to list here.
Also the actor who plays the lead in Clerks, Brian O’Halloran,has cameo roles in the rest of the movies.
Got to love a screenwriter who has a scene discussing felching-he calls it snowballing.
A really obscure one that my friend pointed out to me:
In Boogie Nights, there’s a character named Floyd Gondolli. This character is mentioned in Paul Thomas Anderson’s first movie, Hard Eight.
I’m not sure if this is referential or not, but it always struck me as more than just one star cameoing in another star’s film. To wit, is there anything more than just a cameo when Kevin Bacon races Steve Martin for a cab in “Planes, Trains and Automobiles”?
To the OP: There’s an “Alien” skeleton (or skull) in the Predator’s spaceship in “Predator 2.”
In “Gremlins” the movie title on the theatre marquee was the working title for ET.
Lucas almost always has a reference to his movies.
In Star Wars Leia is in cell number 1138. In fact variations of 1138 and THX show up all of the time as addresses, registration numbers, etc.
Speaking od Star Wars, did anyone else notice that the first time you see the cockpit of the Millinium Falcon, there are two little stainles steel dice hanging above the windsheild? They Don’t show up again, but Chewie brushes them with the top of his head.
In Indiana Jones and the Temple of Doom, the sign on the bar at the beginning was “Club Obiwan.”
The Coen brothers also do it alot.
In Miller’s Crossing, the name of the hotel at the end is the Barton Arms.
Roman Polanski tends to be in most of his films.
In Any Given Sunday, Ben Hur is on the tube during one scene, then Charlton Heston shows up later as the commissioner of football.
It is common for directors to do this sort of thing, or to give Homage to other directors.
