"Thor: Ragnarok" Director Shares 'Purple Guy' Art from SDCC Sizzle Reel

Thor and Hulk were the only major Marvel players missing from "Captain America: Civil War," and we're about to find out what they were up to. "Thor: Ragnarok" will feature both Avengers -- and, as teased in a new Instagram post from director Taika Waititi, it might include supervillain Thanos as well.

The image comes from a sizzle reel screened for attendees at this year's Comic-Con International in San Diego. As mentioned in our panel report for Marvel's Hall H presentation, a comedic, documentary-style short directed by Waititi was screen for fans. The most likely out of continuity doc showed Thor living in New Zealand with a roommate, taking a vacation from his superhero life while also trying to figure out who exactly is "the purple man in the floating chair."

The "purple man" is, of course, Thanos, a villain whose threat has been teased ever since the post-credits scene of 2012's "Avengers." Despite his many appearances, Thanos has yet to cross paths with any of Marvel's heroes. In fact, the Earthly heroes are mostly unaware of the cosmic threat and his hunt for the Infinity Stones; the Avengers have encountered a number of those stones, but remain mostly unaware of their larger, cosmic origin. Thor is the only Avenger that is even vaguely aware of the threat, thanks to a subplot in 2015's "Avengers: Age of Ultron."

We also know that "Ragnarok" will take place mostly off Earth, with Thor and Hulk traveling the cosmos. Props revealed in San Diego confirm that elements of the "Planet Hulk" storyline, which saw the jade giant battling as a gladiator on an alien world, will be included in the film. While this is hardly a guarantee that Thanos will appear in the 2017 film, it's definitely not implausible.

Directed by Taika Waititi and starring Chris Hemsworth, Tom Hiddleston, Mark Ruffalo, Cate Blanchett, Anthony Hopkins, Idris Elba, Tessa Thompson, Karl Urban, Jeff Goldblum and more, "Thor: Ragnarok" arrives in theaters on November 3, 2017.
