‘Doctor Strange’ has become Marvel’s biggest solo movie.

The superhero film – which features Benedict Cumberbatch in the titular role – has grossed $616 million worldwide, surpassing 2008 movie Iron Man’s $585 million, to become the studio’s highest-grossing solo character debut motion picture of all time.

‘Ant-Man’ holds the next place on the list with $518 million, while 2011 movie ‘Thor’ received $449 million, with ‘Captain America’ next with $371 million.

But it is not the most successful Marvel Cinematic Universe motion picture ever as ‘Guardians of the Galaxy’ holds that title after taking $773 million.

The film tells the story of former neurosurgeon Stephen Strange who ventures on a journey of healing after a car accident only to stumble upon the hidden world of magic.

Other stars in the movie include Chiwetel Ejiofor, who portrays Master of the Mystic Arts Karl Mordo, Rachel McAdams, who plays Strange’s fellow surgeon Christine Palmer, and Benedict Wong as Wong.

Cumberbatch recently revealed he had to “step out of his comfort zone” to play the titular character in the film.

He said: “People ask me what I have in common with my character and I feel that’s really it. I was having to do action hero stuff on a level I’ve never done before and wire work and kung-fu moves and casting these spells.

“Amazing movements like tutting with the fingers and all these delicate hand movements as well as body posturing. I was learning that as much as my character was, so both of us were stepping out of our comfort zone so that’s something I could draw on for the characterisation.”
