Doctor Strange
On-set images and video of Doctor Strange have been leaked online Marvel

Marvel's Benedict Cumberbatch-starrer Doctor Strange is currently being filmed in Kathmandu. Over the past few days, several leaked images of the actor and the crew on set have made their way online. Well, that is not all. Now details of the film's purported opening scene, no less, have emerged online.

Latino Review has posted the rumoured description of the sequence. It reveals that the film opens in 1968 Kathmandu where some "Zealots of dark magic manage to open a portal" to a different dimension. "Leading them is a character named Kaecilius, a name taken from a character associated with Baron Mordo in the Marvel Comics," the report adds. The character of Baron Mordo in the film is being played by Chiwetel Ejiofor.

The scene then shifts to present-day New York City where we meet Dr Strange, a gifted but arrogant surgeon. Reportedly, Strange damages his hands in a car accident and even after several surgeries by Dr. Nicodemus West (Michael Stuhlbarg), Strange's hands aren't healed enough for him to be a doctor again.

Apparently his quest for a cure leads him to magic and subatomic particles - already referenced in Marvel's Ant-Man - and eventually to the doorstep of the Ancient One (played by Tilda Swinton). The report says Strange's journey to find the Ancient One is what is currently being filmed in Nepal.

Incidentally, a leaked on-set video (courtesy of Dutourdumonde Photography) shows Cumberbatch filming a scene where his character, Dr Stephen Strange, looks a bit lost. And then at one point, a mysterious hooded figure is seen walking in the opposite direction.

Could this be the Ancient One? Check out the video below. (via ComicBookMovie)

Doctor Strange is slated to release on 4 November, 2016.
