Marvel hosted a special 15-minute IMAX preview of Doctor Strange earlier this week that primarily showed off already released footage and characters. However, as CinemaBlend [via Nerdist] reports, the preview may have also given away the presence of an important character who has remained unconfirmed for the movie up until this point.

Here’s the deal: the preview footage included two sequences that appear to show off Doctor Strange confronting the Dread Dormammu, one of the primary villains from the hero’s comic books. At one point in the preview, there’s a 50-foot head that looks very similar to the depiction of Dormammu in the earliest Doctor Strange comics from co-creator Steve Ditko. CinemaBlend asked director Scott Derrickson about the head and whether it means that Dormammu is involved in the film, to which Derrickson replied, “I’ll never tell. All you get is what you see.”

For those who aren’t overly familiar with Doctor Strange mythos, Dormammu is pretty much the big arch nemesis of the good Sorcerer Supreme. The ruler of the Dark Dimension, Dormammu actually played a role in the origin of Strange after he convinced one of he Ancient One’s (played by Tilda Swinton in the film) followers to turn against his master. Dormammu spends most of his time trying to cross into our dimension in order to take over the Earth and is one of the most powerful beings in the Marvel Universe.

In fact, when Mads Mikkelsen was first cast as the film’s main antagonist, some thought he was playing Dormammu, but those rumors were silenced once it was revealed that he was actually playing Kaecilius, a relatively minor villain in the comics who hasn’t been seen much over the last three decades. Perhaps Kaecilius is actually a minion of Dormammu and Marvel is setting up a confrontation with the big fiery Dread in the next Doctor Strange film. Whatever the case may be, we will find out for sure if Dormammu is involved when Doctor Strange hits theaters on November 4.
