Marty Supreme's original vampire ending was a wild ride, and A24 thought it had to be a mistake. During a recent podcast, director Josh Safdie revealed that the film's initial ending took a bizarre turn, pushing the story far beyond the sports arc audiences got. Marty, played by Timothée Chalamet, was originally written to become a wildly successful businessman after leaving competitive ping-pong. The ending saw him transform a shoe store into a thriving business, leaving New York State, and becoming incredibly wealthy. However, the real twist? Marty was going to be revealed as a vampire. Kevin O'Leary, who plays a ruthless capitalist, was fully on board with the concept, even creating digital teeth for the role. The original ending showed Marty being bitten by a vampire, and it was a shocking twist that left A24 executives confused. O'Leary's character, Milton Rockwell, casually claims he's a vampire, and in the original script, it was taken very seriously. This vampire reveal adds a layer of complexity to the film, showing how far Safdie was willing to push the boundaries, even if it meant leaving the studio questioning the script. But here's where it gets interesting: O'Leary wasn't happy with the final version, feeling Marty and his family got an easy 'kumbaya' ending. He even pitched a darker idea, suggesting Rachel, played by Odessa A'Zion, die in childbirth as a consequence of Marty's selfish choices. While the vampire ending was ultimately cut, it's a fascinating glimpse into the creative process and the potential for a truly unique and controversial film.
