Along with being wild and weird, Doctor Strange is also surprisingly funny. One of the biggest laughs comes when Strange starts settling in to learn from the Ancient One, and Mordo hands him piece of paper with the word "Shamballa" on it. Strange asks if it's his mantra, and Mordo corrects him that it's only the wi-fi password. It's played as a gag, but "Shamballa" also has deeper significance in Doctor Strange's history—and the real world. The concept isn't unique to Doctor Strange, as the mystical, otherworldly kingdom has existed in religious texts for centuries. Into Shamballa is also the name of an important Doctor Strange story from 1986, concerning not only the death of the Ancient One, but also featuring Hamir, the one-handed magic man from the temple. While the comics reveal that Hamir is actually Wong's father, the film flipped the script in so many ways that it's unlikely this relationship will be translated to the big screen.
