"Doctor Strange" released back in November last year and proved to be a big success for Marvel Studios. The character, played by Benedict Cumberbatch, will appear again in "Thor: Ragnarok" and "Avengers: Infinity War." Director Scott Derrickson reveals the full extent of his involvement for these projects and how far ahead Marvel plans.

Marvel Studios does not have a concrete tree of future ideas, Derrickson explained in an interview with Yahoo! Movies. The director elaborated that the studios did not try to force their movies to fit into a specific plan they may have laid out.

"They're doing one movie at a time," he stated. "And just making the next best step, and seeing where that leads. It turns into a really beautiful creative evolution, if you're always looking for the best possible idea for each individual movie."

Derrickson compared the process to the way Marvel icon Stan Lee worked on the comic books. Lee always worked on one comic book at a time instead of trying to plan a year's worth of stories and then forcing each comic book to fit into that structured set-up.

This also means that Derrickson's involvement did not extend any further than the first "Doctor Strange" movie. He explained that the director of "Thor: Ragnarok" and "Avengers: Infinity War" now had the reigns over the character.

It was stated that "Thor: Ragnarok" director Taika Waititi helmed the post-credits scene in "Doctor Strange" and that he enjoyed the final product. Derrickson also commented that he was good friends with the Russo brothers, who will direct "Avengers: Infinity War," particularly Joe Russo.

Doctor Strange will not be appearing in other Marvel films at the time being other than the aforementioned movies but fans can now get a glimpse of more footage that did not make it into the film. A deleted scene has been released, showcasing Doctor Strange helping a dog, /Film reported.

"Thor: Ragnarok" releases on Nov. 3 and "Avengers: Infinity War" will launch on May 4, 2018 . The official trailer for "Doctor Strange" can be viewed below:
