Just as the first trailer for “Captain America: Civil War” has been released, another Phase Three Marvel film is picking up its pace.

JoBlo reports that Marvel’s “Doctor Strange” has officially started production.

Although it has been previously reported that Benedict Cumberbatch was spotted in Nepal filming scenes for the upcoming movie, it was not until recently that Marvel released an official announcement.

Marvel’s announcement details the official cast of the film, a brief synopsis of what the movie will be about and a rundown of the creative team that will be behind the production.

The announcement says that “Doctor Strange” will be produced by Kevin Feige while Victoria Alonso, Stephen Broussard, Louis D’Esposito, Charles Newirth, and Stan Lee will serve as executive producers.

Since “Doctor Strange” belongs to Phase 3 of the Marvel Cinematic Universe, Marvel’s announcement also contains the studio’s objective behind the third phase. The announcement can be quoted as follows:

“Phase 3’s goal—over the course of four years and nine films—is to introduce audiences to new heroes and continue the adventures of fan favorites.”

Still, although reports that shooting has began on the film leaked prior to the official announcement, /FILM points out that the Marvel’s announcement clears some things up.

For instance, Mads Mikkelsen, who was previously reported to be “in talks” for the film is officially joining the cast.

However, the website points out that the characters Mikkelsen and Rachel McAdams will be playing are still a mystery up to this point.

Collider relays that filming for “Doctor Strange” will take place in Hong Kong, London, New York, and Kathmandu, Nepal.

The website also highlights that “Doctor Strange” is important to the MCU since it will introduce the film universe to the realm of mysticism.

“Doctor Strange” will star Benedict Cumberbatch as Stephen Strange, along with Chiwetel Ejiofor, Mads Mikkelsen, Rachel McAdams, Michael Stuhlbarg and Tilda Swinton.

It is scheduled to open in theaters on November 4, 2016.
