Among the new characters that are all set to debut in Phase 3 of the Marvel Cinematic Universe, one of the most anticipated one is the famous sorcerer, Doctor Strange.

Based on the Marvel comic book character of the same name, Doctor Strange made his debut in 1963 and since then, has been one of the all-time favourite characters among comic book fans.

There have been a lot of speculations whether the upcoming live action movie will be about his origin or not. Kevin Feige, president of Marvel Studios, confirmed that the movie is about the origin of the Master of the Mystic Arts, who once used to be a neurosurgeon.

During the promotional event of DVD/Blu-Ray release of "Avengers: Age of Ultron," he said that the origin story will be the prime plot of the upcoming movie.

In a Q&A session with IGN in the event, he said, "Doctor Strange has one of the best, most classic, most unique origin stories of any hero we have, so why wouldn't we do that? That was sort of always the plan.

"How you tell that origin, perhaps there are ways to twist it or play with that, but for the most part, it's a gift when the comics have something with such clarity of story and of character. That doesn't always happen in the comics, and when it does, you use it."

Director of photography, Ben Davis, said that "Doctor Strange" is going to be dark and will have a "psychedelic grounding." In a previous report, he also described the upcoming film as "Marvel's fantasia."

The lead role of Doctor Stephen Strange will be played by "Sherlock" star Benedict Cumberbatch while Tilda Swinton will play the character of The Ancient One. Swinton, who is known for her role in "Motherhood Trilogy" of films, said she does not know yet whether she will play The Ancient One as a man or a woman.

Realty Today has reported that Rachel McAdams is all set to join the cast. However, no information regarding her role has been revealed yet. During the Toronto Film Festival, McAdams hinted that her role is going to be "psychedelic."

Feige stated that McAdams role is "big and significant." He stated, "She represents a certain point of view of the worlds that we experience in the movie."

According to the speculations, McAdams may play the character opposite to Cumberbatch, either his great love Clea or Victoria Bentley. She could also be the mystic student and author Morgana Blessing or the mystical entity "The Vishanti."

"Doctor Strange" is all set to hit theatres on 4 November, 2016.
