Doctor Strange in the Multiverse of Madness writer Michael Waldron has revealed some of his inspirations for the upcoming sequel, and they might not be what you'd expect.

He told Vanity Fair that the late chef and traveller Anthony Bourdain and the fictional adventurer Indiana Jones were two of his inspirations for the sequel. Stephen Strange and Bourdain are obviously very different in a lot of ways, but Bourdain had an "intense intellect" not unlike Strange, Waldron said.

"I gravitated toward Anthony Bourdain," Waldron said. "Strange is an elitist as a neurosurgeon and a sorcerer. Anthony Bourdain was a man of the people, but there was that intense intellect. You always felt like he could eviscerate anybody with his words at any time. But yet, Anthony Bourdain never really punched down. That was the first ingredient in the stew for Doctor Strange.
