Rachel McAdams can't take eyes off Cumberbatch's 'extraordinary' Doctor Strange

Actress Rachel McAdams says she finds Benedict Cumberbatch's transformation into Doctor Stephen Strange "really extraordinary".

The 37-year-old actress, who plays the role of Doctor Christine Palmer in the fantasy film, said she could not take her eyes off of her co-star, reported Female First.

"I play an ER trauma doctor who specialises in thoracic surgery, at the Metropolitan Hospital in New York City. Stephen is a very famous, successful neurosurgeon at the same hospital that she works at. They are former boyfriend and girlfriend when we pick up in the story. So we start at the end of their relationship, which is a little bit different. It's not a classic love story, which I thought was really clear. Tilda looks incredible as the Ancient One. You can't take your eyes off of her and the same with Benedict. His transformation into Strange is really extraordinary," McAdams said.

Cumberbatch plays the lead role in the movie.
