WATCH | The special features section of "Doctor Strange's" Blu-ray and DVD (arriving Feb. 28) reveals the secret to the movie's magic: a hip-hop choreographer by the name of Julian Daniels.
Daniels, a.k.a. JayFunk, has studied hip-hop for 10 years and earned a black belt in karate.
Specializing in tutting (whose movement is limited to hands and arms), he taught "Doctor Strange" actors the motions that were used to cast spells in the film.
Count "Doctor Strange" star Benedict Cumberbatch among Daniels' fans.
Daniels has 20,000 followers on Instagram, where he often posts videos of himself tutting.
