Recently it was confirmed that Community writer Don Harmon has been brought on board the Doctor Strange movie to do some additional last-minute scenes; however, the news about Harmon on Doctor Strange was first revealed accidently at Comic-Con.
Don Harmon was a part of the Harmontown podcast at the SDCC where he showed off how to screenwrite during a live writing segment. A fan in attendance managed to record the event and took a screen shot of Harmon's assitance's computer which shows off that Harmon has been working on Doctor Strange.
The screenwriting program reveals that Doctor Strange confronts Dormammu as well as scenes involving Mads Mikkselsen's character Kaecilius' seduction, and numerous scenes involving a magical mystery, new church and rituals. A reference also seems to be made to a Mirror Realm.
