For anyone still wondering what the subtitle means in Thor: Ragnarok, the cast and director of the film help set fans straight. With just a few more weeks until Marvel's final film of the year arrives, marketing has continued non-stop for the movie. And it seems to be paying off, as fans are engaged and buzzing across social media. Meanwhile, early reactions to the film from critics are overwhelmingly positive. Marvel has even managed to turn the one potential stumbling block for the film into a promotional opportunity.

When Marvel Studios announced the third Thor film would be called Ragnarok, comic book and Norse mythology fans were ecstatic. For the average moviegoer, however, the name probably sounds like nonsense. And while the confusion is unlikely to deter many people from seeing the film, the minds behind the movie saw a chance to have a little fun.

Yesterday, Marvel Studios used their Twitter to ask fans #WhatsRagnarok? The best responses were then addressed by Chris Hemsworth, Jeff Goldblum, Tessa Thompson, Mark Ruffalo, and director Taika Waititi. While their are a lot more than we could post, here are a few of the best ones.

Check out the hashtag or Marvel's account for a lot more from the cast and crew. And while they're all charming, Goldblum's Antics with Semantics are the highlight of his various responses. But enjoyable though they may be, they fail to answer the question: just what does 'Ragnarok' mean?

In Norse mythology, Ragnarök is a sort of apocalyptic cycle that the world and the gods endure. During the event, many gods die, natural disasters cover the land, and the world is eventually drowned and reborn. Many of the gods return and the cycle continues, though some changes and renewed understanding tend to follow each cycle. Given that Thor stories in the comics draw heavily from Norse mythology, Ragnarök in Marvel Comics is much the same. At times, however, it's been used to foretell a more permanent form of doom. It also tends to involve characters like Loki, Hela, and Surtur sowing chaos.

For the film Ragnarok, the name is more an homage and an evocation of the destruction that's coming for Asgard. Many of the prominent figures from the story in the comics will also appear in the film, and their motivations may even align. But like Captain America: Civil War, the name is more of a nod to the source material than a strict adaptation. And the less said about the clone of Thor named Ragnarök from the comic book Civil War, the better.
