Remember that awesome fight scene between Hulk and Loki in the first Avengers movie? Sounds like we're finally getting a rematch! With production set to begin on Thor: Ragnarok this summer, Marvel has already started beefing up the cast. Last month, it was announced that Jeff Goldblum has come aboard to play The Grandmaster with Karl Urban portraying Skurge. And Tessa Thompson has been confirmed as Valkyrie. There have been plenty of rumors swirling around about the plot, although nothing has been confirmed by Marvel quite yet. During a convention appearance this weekend, star Chris Hemsworth explained more about the story, with Tom Hiddleston teasing what could be a show stopping scene that brings down the house.

Thor and Thor: The Dark World co-star Tom Hiddleston appeared at the Wizard World Philadelphia convention, where part of their panel was posted on YouTube. The panel's moderator asked Tom Hiddleston what fans can expect from Thor: Ragnarok, and while he wouldn't delve into specifics, he did talk about Mark Ruffalo showing up as The Hulk. Here's what the actor had to say below, teasing an epic rematch between Hulk and Loki.

"Lets not forget that its no secret that the Hulk shows up in Ragnarok, and the last time Loki and Hulk were in the same room didn't go very well for Loki. So, he's got a few chips on his shoulder, but it's fun, you'll see."

Tom Hiddleston is obviously referring to the scene from 2012's The Avengers, where Hulk tossed Loki around like a rag doll, before delivering the infamous line, "Puny god." When Chris Hemsworth was asked about the movie, he teased that we will get to see a new world that hasn't been seen before, and "different" takes on both Thor and Loki.

"Man, it is a lot of fun. I think tonally it's a big shift in a great way, more than anything we've seen before. Taika Waititi, the director, if you know any of his work, yeah, he's just an incredible sort of comedic talent, a lot of heart in everything he does, but you know it's a very different Thor, it's a different Loki, I think there's a - we go off on another world that we haven't experienced before. It's fun you know, but that's me skirting around the issue because I can't say too much."

Marvel's Kevin Feige has stated in the past that most of this movie is set in the "cosmos," which explains a recent report that Natalie Portman won't be reprising her role as Jane Foster, and Stellen Skarsgard also isn't coming back as Erik Selvig. The story reportedly finds Loki teaming up with the villainous Hela (Cate Blanchett), who banishes Thor from Asgard and destroys his hammer Mjolnir. Thor then encounters a gladiator planet where he's forced to face the current champion, Hulk. This reportedly leads to a "cosmic road trip" with both Hulk and Thor. The movie is also being called a Planet Hulk mash-up, as we won't get a solo Hulk movie for quite some time.

Taika Waititi is directing from a script that was worked on by Christohper Yost and Craig Kyle, with revisions by Stephany Folsom. Production is slated to begin this summer in Australia, with Marvel already setting a November 3, 2017 release date. While we wait for more details on Thor: Ragnarok, take a look at the videos from Wizard World below, with both Chris Hemsworth and Tom Hiddleston.
