- In the comics, Sakaar was near a single wormhole called the Great Portal. Hulk was exiled to Sakaar by the Illuminati, where he became a powerful gladiator and led an uprising against the Red King, the ruler of the planet.
- The buildings of Sakaar are made up of an assortment of scrap metals.
- Taika Waititi stated that he wanted to evoke Jack Kirby's distinct art style in the buildings of Sakaar.
- On the Grandmaster's building there are sculptures of Man-Thing, Beta Ray Bill, Ares, and Bi-Beast alongside Hulk. Those characters were presumably the previous champions of Sakaar's arena.
