Rachel McAdams hasn't ruled out starring in Marvel's 'Doctor Strange'.

The 'Southpaw' actress has a tight schedule, but hinted ''it's still super-early days'' with regards to playing the female lead in the film, which she would star alongside British actor Benedict Cumberbatch, if she agreed to take on the part.

She told the LA Times: ''it's still super-early days, and I don't know where that's gonna go, if it's gonna go anywhere at all.''

Marvel have had many top Hollywood actresses make their debut in the comic book world, including Natalie Portman in 'Thor' and Scarlett Johannson who plays Black Widow in 'Avengers: Age of Ultron'.

However, the blonde beauty doesn't believe in following suit when it comes to picking the films for her because she doesn't think it's ''everything''.

She added: ''I try to shut out ideas about why you should do things. Trying to do good architecture and really designing a career? There's some attention to be paid to that, but I don't think it's everything.''

The cast of 'Doctor Strange' includes the 'Sherlock' actor and 'Trainwreck's' Tilda Swinton and will begin filming in November.
