Ghostbusters: Frozen Empire director Jason Reitman is set to trace the tumultuous first night of SNL in his new film Saturday Night, and we now have our first look at the cast of what Reitman calls “a comedy-thriller.” Starring the likes of Gabriel LaBelle as Lorne Michaels, Dylan O’Brien as Dan Aykroyd, Matt Wood as John Belushi, and Ella Hunt as Gilda Radner, Saturday Night will unfold in real time over the course of 90 minutes, and show just what it took to bring Saturday Night Live into homes everywhere on October 11, 1975.
