Rumor of the day: This actress could be the female lead in Doctor Strange

With casting continuing for Marvel's Doctor Strange, speculation has now turned to the movie's female lead.

Heroic Hollywood reports that Rachel McAdams has been offered an opportunity to join Benedict Cumberbatch (Stephen Strange), Chiwetel Ejiofor (Baron Mordo) and Tilda Swinton (The Ancient One) in director Scott Derrickson's (Sinister) adaptation of the Sorcerer Supreme's origin story. 

McAdams is currently starring in the second season of HBO's True Detective, but she's also shown up recently in last year's excellent A Most Wanted Man and this year's Aloha, with a role in the boxing drama Southpaw coming up later this month as well.

What is not known is just what character McAdams will be playing in Jon Spaihts' (Prometheus) screenplay. The most obvious choice at this point would be Clea, who was introduced by Stan Lee and Steve Ditko in Strange Tales #126 (November 1964) and eventually became the student, lover and wife of Stephen Strange. 

A sorceress herself, Clea is the daughter of Umar, sister of major Doctor Strange villain Dormammu, who is the ruler of the mystical realm known as the Dark Dimension. At one point Clea becomes Sorceress Supreme of the Dark Dimension and lords over it herself, estranging herself from Doctor Strange in the process.

If McAdams is indeed playing Clea, it remains to be seen how much of that backstory makes it into the movie. McAdams could also be playing a completely new character created expressly for the film. We'll probably learn more if and when she officially signs on. 

Production starts this November on Doctor Strange, with its release scheduled for Nov. 4, 2016. Calling all diehard Strange fans out there -- would you like to see Rachel McAdams as Clea?
