Rachel McAdams is to star in Marvel's 'Doctor Strange'.
The 36-year-old actress - whose previous film credits include 'The Notebook' and 'Southpaw' - had been widely tipped to appear opposite Benedict Cumberbatch in the movie studio's latest creation.
She said: "I am going to go and do 'Doctor Strange'. A Marvel ... a kind of psychedelic Marvel comic with Benedict Cumberbatch. So yeah, I'm really looking forward to that."
However, at Marvel's insistence, Rachel remained tight-lipped about the specifics of her role.
Asked what she could reveal about her character, she told TheWrap: "I don't know if I can."
Despite being among the most in-demand actresses in Hollywood, Rachel recently confessed she never wanted to become a movie star as a child.
Musing on whether she ever dreamed of being a big screen starlet, she said: "I think it was sort of a vague idea in my mind when I was a kid, when you think, 'What would that be like?' But it wasn't something I really meditated on or planned for in any way.
"I really thought I'd be doing theatre in Canada. I'd grown up doing children's theatre there, and I always imagined myself being artistic director of a children's theatre company."
