'Thor: Ragnarok' premiere date, news, plot rumors: Thor to fight the Hulk in a gladiator arena

The third installment to "Thor" will be showing in 2017, and it might entail a battle between Thor (Chris Hemsworth) and the Hulk (Mark Ruffalo). Meanwhile, the upcoming Marvel films have sparked several theories about the last missing infinity stone and who is keeping it.
"Thor: Ragnarok" is expected to debut in November 2017, and it is directed by Taika Waititi, Christopher Yost, and Craig Kyle. According to IB Times, the film will revolve around Thor and his mission to find all of the Infinity Stones. The conflict will unveil when Thor crosses paths with Loki (Tom Hiddleston), who shapeshifts as his father, Odin (Anthony Hopkins).
According to Movie News Guide, Loki will not be the only one that Thor will be crossing paths with. It is anticipated that Thor will be traveling the universe throughout the film and stumbles upon the Hulk in a gladiator arena in an unknown planet.
Thor will be forced to battle with the Hulk, who was taken to become a slave by the Grandmaster (Jeff Goldblum). Other details about their fight are kept under wraps, but it is expected that the two will find themselves working together in "Guardians of the Galaxy Vol. 2."
Meanwhile, there are several theories circulating on the Internet regarding the character who has the last Infinity Stone.
Moviepilot suggested the T.H.A.N.O.S. theory that could help uncover those who possess Infinity Stones.
Each letter of the word has a specific meaning that is connected to the whereabouts of an Infinity Stone. T refers to the Tesseract (Space Stone), A is Aether (Reality Stone), O stands for Ord (Power Stone), and S stands for Scepter (Mind Stone). The meaning of letter N was only recently discovered when "Doctor Strange" was released. N stands for Necklace, which points to the Eye of Agamotto as the Time Stone.
What the letter H stands for is still unknown as it could mean many different things. For one, the Soul Stone could be in the hands of the Goddess of Hel, Hela (Cate Blanchett). Meanwhile, another possible theory is that it could mean Hammer, which indicates that the stone is in Thor's Mjolnir.
It is also possible that Heimdall (Idris Eba) could have the Soul Stone for safe keeping because his eyes appear to have the same color as the stone. It is also rumored that the Stone gives him the power to see across the universe, according to Comicbook.
"Thor: Ragnarok" is expected to premiere on Nov. 3, 2017.
