Rachel McAdams has confirmed she is in talks to star in 'Doctor Strange'.

The 36-year-old actress was reported to be the front runner to play the female lead in the Marvel movie opposite Benedict Cumberbatch, who will portray the titular superhero.

Now McAdams has confirmed negotiations are ongoing about her joining the blockbuster and she's interested in the role.

Speaking to the Los Angeles Times newspaper, she said: ''It's still super-early days, and I don't know where that's gonna go, if it's gonna go anywhere at all.''

McAdams isn't concerned about the film's outlandish plot because she's not a ''comic book snob''.
