Steven Spielberg sees an announcement that "Eternals 5" will be four hours long. A peaceful expression passes over his face. He calmly walks to the nearest movie theater, buys a random ticket and a big bag of buttered popcorn and gets a seat near some other moviegoers. He looks over to his left: he's surprised to see Tom Cruise, nodding reassuringly. Who’s next to Tom? Francis Ford Coppola. James Cameron is a few seats up with Paul Schrader. Countless other artists and filmmakers are also there.
Everyone looks at each other with a melancholy but true smile. It takes a minute, but they all eventually understand why they’re here. Finally, Martin Scorsese comes in and sits down next to Steve and Tom, saying “Sorry I’m late!”. But they just broadly clap him on the shoulder.
Then the lights go down, and the movie starts: It's black-and-white footage of a train coming towards the camera. Then the train crashes out of the screen, exploding into the theater, leaving no survivors. The End of Movies.
