I am good at keeping secrets: Benedict Cumberbatch

He is one of the few stars who knows how the story of "Avengers: Infinity War" unfolds, but do not expect any spoilers from Benedict Cumberbatch as he says he is 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.

"It doesn't make a difference. I will be sitting in the premiere and going like, 'Did I read that?'. A Marvel film is never what it is on script and that's what the joy is. There is a great fluidity and improvisation," he said.

Set to release on April 27, "Infinity War" is the biggest superhero saga to be witnessed by the audiences ever, with fan favourites such as Captain America, Iron Man, Spider-Man, the Hulk, Black Widow, Thor, Black Panther among others, joining forces to defeat the most powerful villain, Thanos.

And while fans are curious as to who emerges unharmed in the climax, Cumberbatch said the film is all about staying "united".

"We strongly stand together. 'We are united' that's what the feeling you get from the Avengers. It is about putting away your differences and uniting. These Marvel films always bring people together. They always have science, logic, social and political tones. This one is about 'United We Stand'."
To which Cumberbatch funnily replied, "There wasn't any joke and I hope there isn't any in future."
