<Li> Mads Mikkelsen as Kaecilius: A Master of the Mystic Arts who broke away from the Ancient One . A combination of several antagonists from the comics, Kaecilius was used in the film to drive the introduction and development of bigger villains for the future, including "certain individuals who live in other dimensions". Derrickson compared this dynamic to that of Saruman and Sauron in The Lord of the Rings, giving the film a "huge and fantastical" villain like Sauron, but also having "human relateability" with Kaecilius, like Saruman, for Strange to face throughout the film . Derrickson admitted that Marvel's villains are often criticized, and noted that MCU films dedicate little time to developing antagonists . For Doctor Strange, he just hoped to show "Kaecilius's point of view and what makes him tick" in the time that he could, feeling that the character is a "man of ideas" with "watertight logic" like John Doe from Seven and the Joker from The Dark Knight . On these motivations, Feige explained that Kaecilius believes the Ancient One is a hypocrite, protecting her own power base, and that the world may be better off "if we were to allow some of these other things through ." Mikkelsen's makeup took between 2 - 3 hours to apply . </Li> <Li> Tilda Swinton as the Ancient One: A Celtic mystic, who becomes Strange's mentor . The character in the comics is a Tibetan man, a situation which co-writer C. Robert Cargill compared to the Kobayashi Maru, an unwinnable training exercise in the Star Trek universe . He explained that adapting the character as the comics portrayed him would be realizing the major Asian Fu Manchu stereotype, and would involve the film with the Tibetan sovereignty debate, but not giving one of few significant Asian roles to an Asian actor would also understandably be received negatively . Derrickson wanted to change the character to an Asian woman, but felt that an older Asian woman would invoke the Dragon Lady stereotype, while a younger Asian woman would be perceived as exploiting Asian fetish and "a fanboy's dream girl". To avoid the character filling any of those three stereotypes, or enabling the stereotype of a "Western character coming to Asia to learn about being Asian", Derrickson decided to cast a non-Asian actor in the role, but to still take the opportunity to cast "an amazing actress in a male role". Feeling that Swinton was the obvious choice to play "domineering, secretive, ethereal, enigmatic, (and) mystical", Derrickson wrote the Ancient One in the film specifically for the actress, before she was offered the role . Additionally, though the film uses the terms "her" and "she", Swinton chose to portray the character as androgynous, while Feige explained that the Ancient One and Sorcerer Supreme are mantles in the film held by multiple characters through time, so a more comic - accurate Ancient One could exist within the MCU . Still, Swinton's casting was widely criticized as whitewashing . In response to this, Derrickson said that though he was pleased with the diversity of the film's cast, in terms of both gender and ethnicity, "Asians have been whitewashed and stereotyped in American cinema for over a century and people should be mad or nothing will change . What I did was the lesser of two evils, but it is still an evil ." </Li> <P> Cumberbatch also portrays, uncredited, the villainous entity Dormammu . The actor suggested he take on the role to Derrickson, feeling that having the character be a "horrific" reflection of Strange would work better than just "being a big ghoulish monster". The director agreed, elaborating that the casting implies that Dormammu does not have a normal physical form in his own dimension, and so is simply imitating Strange for their confrontation . To create the character, Cumberbatch provided motion - capture reference for the visual effects team, and his voice was blended with that of another uncredited British actor, whom Derrickson described as having "a very deep voice". The producers also had Tony Todd record voice over for Dormammu as an alternative to Cumberbatch, but ultimately decided on using Cumberbatch for the voice . </P> <P> Chris Hemsworth reprises his role of Thor from previous MCU films in the film's mid-credits scene . Additionally, Linda Louise Duan appears, unnamed, as Tina Minoru, Mark Anthony Brighton portrays Daniel Drumm, and Topo Wresniwiro portrays Hamir, all Masters of the Mystic Arts under the Ancient One . The latter is based on Hamir the Hermit, Wong's father in the comics, who was the Ancient One's personal manservant . The character is neither a manservant nor Wong's father in the film . Zara Phythian, Alaa Safi, and Katrina Durden portray zealots under Kaecilius, and Pat Kiernan appears as himself . Doctor Strange co-creator Stan Lee makes a cameo appearance as a bus rider reading Aldous Huxley's The Doors of Perception . Amy Landecker was cast as anesthesiologist Bruner, but the majority of her role was cut from the finished film . </P>
