Marvel and IMAX may have announced the core cast of their groundbreaking series, "Inhumans," however, a Twitter post from an actor has revealed there are still some roles left to be filled. In a tweet that has since been deleted, actor Chad James Buchanan revealed (via ScreenRant) that he was heading to Hawaii, where the series has been filming for a few weeks now, to begin work on the highly anticipated series in an undisclosed role.

Not much is known regarding Buchanan's role in the series, however, with the Royal Family having already been cast, it's more than likely he'll either be playing an antagonist of sorts -- especially given the latest synopsis for the series -- or a possible "NuHuman." We've already seen one of the NuHumans make their way to television with the addition of Lash on "Agents of S.H.I.E.L.D." last season, but with "Inhumans" writer Charles Soule having confirmed the inclusion of more NuHumans on the "Inhumans" television series, it's entirely possible that Buchanan has been cast as one of the newer characters.

Buchanan is an up-and-coming actor who, although hasn't really landed a breakout role thus far, has a rather impressive list of credits to his name, including "Jane the Virgin," "Glee," and "Grey's Anatomy." Those eager to see what the actor could possibly add to a series like "Inhumans" can currently catch Buchanan in the series regular role of Hunter Morgan on Fox's "Star."

The eight-episode series centers on the Royal Family of the Inhumans, a race of genetically advanced humans with extraordinary powers introduced in 1965 by Stan Lee and Jack Kirby in Marvel’s “Fantastic Four.” The first two episodes, filmed entirely with IMAX cameras, will premiere Sept. 1 in IMAX theaters, two weeks before the show’s broadcast debut Sept. 26 on ABC.

“Inhumans” stars Anson Mount as Black Bolt, Iwan Rheon as Maximus the Mad, Serinda Swan as Queen Medusa, Ken Leung as Karnak, Isabelle Cornish as Crystal, Eme Ikwuakor as Gorgon, Mike Moh as Triton and Sonya Balmores as Auran.
