'Doctor Strange' is one of those properties that Marvel Studios President/producer Kevin Feige is mystically passionate about, and one that will bring the supernatural element of the comic book universe to the 'Avengers' films. Feige even said that it was in "active development," so why wasn't the movie featured or, at the very least, officially announced at Comic-Con 2014?

We caught up with Feige on the press line after the big 'Ant-Man' and 'Avengers 2' panels on Saturday night and got the lowdown. Turns out, it's a simple case of details not being finalized. From our video above, he said:

We announce things when we're ready to announce them. As we talked about with 'Guardians 2,' that was ready. There are a lot of plans, and you can't reveal all of them at the same time.

Horror director Scott Derrickson of films like 'Deliver Us From Evil' and 'The Exorcism of Emily Rose' is onboard to helm 'Doctor Strange' and 'Prometheus' screenwriter Jon Spaihts is working on the script, while Joaquin Phoenix is in negotiations to take on the title role. However, it's likely Phoenix had not signed on in an official capacity prior to the Comic-Con panel, hence the film wasn't revealed.

Earlier, Feige described 'Doctor Strange' to us as a "crazy acid-trip way of traveling through dimensions and traveling through realms," and he said the film would play with the notion of science as an explanation for "how the sorcerers do what they do."

With the current plan for Marvel to release at least one sequel and one new property each year (2017 and 2018 currently have three movie dates set), we predict that remaining 2016 release slot (July 8, 2016) will host 'Doctor Strange,' though we'll report back with an official announcement when one is made.
