Phase 2 of Marvel Studios' cinematic universe officially wrapped up earlier this year with Ant-Man, while Phase 3 will kick off next year with the Avengers-packed Captain America: Civil War. Though Civil War will introduce new heroes to the MCU like Black Panther and Spider-Man, the studio's second release of 2016, Doctor Strange, will be a standalone origin story for the titular hero.
Marvel revealed concept art for Doctor Strange at Disney D23 Expo in August, but little is known about the film aside from its main cast: Benedict Cumberbatch as Stephen Strange, Tilda Swinton as the Ancient One, Chiwetel Ejiofor as villain Baron Mordo and Rachel McAdams as the love interest (perhaps Night Nurse). However, filming on Doctor Strange began earlier this week in Nepal, giving fans a first look as Cumberbatch as Strange, and now new photos show Ejiofor suited up as Baron Mordo.

According to recently released rumors about the plot of Doctor Strange, the sequence currently filming in Nepal is part of Strange's journey to find the Ancient One for help healing his hands after they were injured. Further according to the report, Kathmandu, Nepal, will be the location where, in the past, a portal was opened to another dimension by "Zealots of dark magic" led by Kaecilius - a character from the comics who worked for Baron Mordo.
In the comics, Baron Mordo was a student of the Ancient One, but turned against his master and became an antagonist to Stephen Strange. Since Doctor Strange is an origin film, and since Strange and Mordo appear to be friendly when they first meet, the film could depict Mordo's turn from student to villain. However, with Mordo's possible ties to Kaecilius still a mystery and much of his character details unknown, it's difficult to say if this character arc will appear in the final Doctor Strange film.
As for Baron Mordo's costume, the design for Doctor Strange appears to retain the character's customary green color, though the suit seems to be a looser and more modern take on the villain’s costume from the comics. Given that the concept art from D23 depicted a Doctor Strange costume matching the character, it seems likely that the film will do the same with Baron Mordo, with another suit more closely tied to the comics coming later in the film. But, of course, we'll need to wait for more set photos or officially released images from Doctor Strange before we know more about what to expect from Ejiofor’s Baron Mordo.
