Thor: Ragnarok VFX supervisor Jake Morrison is especially keen on Bill eventually debuting in live action, and even included a subtle nod to him in the third Thor movie by having him be one of the faces adorning the tower attached to the Sakaar gladiator arena.
Beta Ray Bill has appeared in a handful of animated TV shows, video games and the animated direct-to-video movie Planet Hulk, but a theatrical appearance would expand his fanbase significantly, as has been the case with so many previously obscure characters who were eventually brought into the MCU.
