An Avengers: Infinity War's joke aimed at Iron Man by Doctor Strange was totally improvised by Benedict Cumberbatch.
Fans may recall the Sorcerer Supreme's response to Tony Stark's quip, "What exactly is your job besides making balloon animals?", which goes: "It's protecting your reality, douchebag..."
In conversation with The Hollywood Reporter, Cumberbatch recalled shooting this particular scene in New York City.

"I remember on the set when I called him a douchebag, there was this sort of ripple effect," he began.
"'Oh my God. Did you just call Iron Man a douchebag?' They kept it, good for them. And then, it got the same kind of response at the cinema.

Away from saving the universe in a red cape, Cumberbatch will soon be seen in Netflix's The Power of the Dog opposite Kirsten Dunst, Jesse Plemons and Kodi Smit-McPhee.
Directed by Jane Campion (The Piano), this revisionist western finds the actor breathing life into the "brutally beguiling" Phil Burbank whose power and fragility is trapped in the past and in the land.
Phil is a wealthy rancher alongside his brother George (Plemons) and their lives are altered forever when they meet widow Rose (Dunst). He behaves cruelly towards Rose and her son Peter (Smit-McPhee), only for George to comfort her and return to marry her.
When George brings them both back to the ranch, Phil's taunting of the pair takes on an eerie form.
The Power of the Dog will stream on Netflix this December.
