'Thor: Ragnarok' cast news, spoilers: Thor and armored Hulk battle it out; Fire demon Surtur revealed

Thor (Chris Hemsworth) will be fighting an armored Hulk (Mark Ruffalo) in "Thor: Ragnarok," the third installment in Marvel's "Thor" franchise.

In a sizzle reel shared during the film's Comic-Con panel on Saturday, July 23, Gladiator Hulk, the armored version of the Avenger's temperamental green giant, was revealed for the first time in a CGI test footage. Thor encountered Gladiator Hulk, who had on a helmet, a gauntlet and a weapon, in what may be Planet Hulk.

According to Time, along with the test footage, the "Ragnarok" video showed actual footage from the upcoming film along with some concept art.

The video was one of two "Thor" teasers dropped at Comic-Con this weekend. The other was a light-hearted mockumentary showing what Thor and Hulk were up to during the events in "Captain America: Civil War" (2016). According to ComicBook.com, in this video, Thor hangs out in Australia with a new roommate named Daryl as the rest of the Avengers are battling it out in Berlin.

"I just am taking a break," Thor says in the video. "We had this cool adventure saving New York, that was pretty great. So I moved to Australia and moved in with Daryl."

In the documentary-style video, Thor says that he is taking some "me time" but is miffed when Tony Stark (Robert Downey, Jr.) calls Hulk but not him. His new roommate helps him compose an email addressed to Stark and Steve Rogers (Chris Evans) in which he talks about their "relationship problems."

Both "Thor" videos were shown exclusively at Comic-Con 2016 and will not be made available online.

Meanwhile, the two main villains in "Thor: Ragnarok" have finally been confirmed. The sizzle reel unveiled at Comic-Con showed Cate Blanchett's Hela for the first time and also revealed a surprise villain: Surtur, the fire demon of Muspelheim.

In the comics, Surtur is an immortal who plays a critical role in the Ragnarok.

Principal photography on "Thor: Ragnarok" began on July 4.

The film hits theaters Nov. 3, 2017.
