Following yesterday's massive Marvel Studios Hall H panel, Thor: Ragnarok director Taika Waititi revealed that Clancy Brown, who has done voice over work for shows such as Avengers Assemble and Star Wars Rebels, would be voicing Surtur in the film. Waititi revealed the news to ComicBook.com, explaining that he did some of the motion capture for the character, but that the voice was handled by Brown.

"I did a little of the mo-cap stuff for Surtur, body wise, but then we have Clancy Brown doing the voice of Surtur."

Although Surtur has been confirmed to appear in the film for some time, it wasn't until the latest trailer for Thor: Ragnarok that we got our first look at the character on the big screen. Surtur, who is based on the fire giant from Norse mythology, first appeared in Marvel Comics back in 1963 and has served as a recurring Thor villain ever since, playing a key role in the events of Ragnarok.

Along with his work on Avengers Assemble and Star Wars Rebels, Brown is also credited with voicing Mr. Krabs on Spongebob, as well as Parallax in 2011's Green Lantern, which funnily enough also featured Thor: Ragnarok director Taika Waititi as Tom Kalmaku.

Directed by Taika Waititi, Thor: Ragnarok stars Chris Hemsworth as Thor, Tom Hiddleston as Loki, Cate Blanchett as Hela, Idris Elba as Heimdall, Jeff Goldblum as Grandmaster, Tessa Thompson as Valkyrie, Karl Urban as Skurge, Mark Ruffalo as Bruce Banner/the Hulk and Anthony Hopkins as Odin. The film will hit theaters on November 3rd.
