Doctor Strange: 31 Easter Eggs & References You Must See
23. The Pop Culture References
The film oddly features a number of pop culture references when Doctor Strange is trying to break the ice with Wong. He asks if he just has a single name "like Adele" and then proceeds to mention Bono, Eminem and Drake as well as Aristotle.
And then later when the pair meet again, Strange sasses Wong and mentions Beyonce, who Wong seems not to recognise, only to be revealed in the next scene to be listening to her on his walkman.
The "cameo" was actually down to Cumberbatch himself...
