'I am good at keeping secrets'

The 41-year-old actor, who plays Doctor Strange in the much-awaited movie, said it was not a curious fan in him, but an old-school performer that demanded the script from Marvel.

"I am kind of old-school in terms of filmmaking. I don't know how I managed to get the complete script. I am good at keeping secrets. As a fan, I didn't want to know what was going on, but as a character I had to understand the bracket in which I had to be operating. I had more reasons, other than curiosity," Cumberbatch said in a group interview here.

Marvel has been very guarded throughout the production of Infinity War. So much so that directors Joe and Anthony Russo kept the full script out of the stars' hands; only providing them with their scenes.

At the beginning of the worldwide promotional campaign of the film, the duo also put out a letter appealing to the fans to keep spoilers to themselves.

Cumberbatch said reading the script made no difference as he is confident that there will be many more surprises for him when he finally catches the film at its premiere.
