Thor: Ragnarok - 10 Huge Spoilers From The Comic Con Trailer
4. The Beta Ray Bill Easter Egg
As was quickly spotted by fans in the wake of the trailer's release, Sakaar has a giant monument to some of the champions who ruled the arena before Hulk got there, and some of them are familiar figures from Marvel lore.
The planet's skyline is dominated by a huge totem adourned with busts of the likes of Beta Ray Bill, Ares, Man-Thing and Bi-Beast, suggesting that The Grandmaster has been in the business of fight fixing for some time.
Whether we'll actually get to see any of these characters on screen remains to be seen, but there have been long-running rumours that Bill would appear at some point in the MCU. He'd definitely work as a veteran fighter who tells Thor the lay of the land and helps him out with his escape plan.
