Thor: Ragnarok - 10 Questions We Still Have

Thor: Ragnarok will come thundering onto cinemas next month and the hype is at almost white-hot levels thanks to those epic trailers, complete with neon-drenched synthesizers, in-depth Norse mythology and a healthy dose of Armageddon.

Chris Hemsworth's third outing as Marvel Comics' famous thunder good is already a more exciting offering than its dismally disjointed predecessor, The Dark World, and not just because it has a shedload of Hulk in it.

Cate Blanchett's big bad Hela has the potential to be one of the greatest villains ever to set foot in the Marvel Cinematic Universe, if what they've shown so far is anything to go by, and the lighter, zanier tone is a welcome change of pace for Thor.

The stakes promise to be higher this time around, as Blanchett's goddess of death is about to unleash the Norse apocalypse on Asgard, and the images of mass destruction in the trailers suggest Thor will have his work cut out stopping it.

At least he's got a team to watch his back this time, though with the unpredictable god of mischief Loki among its ranks, is that really such a good thing?

This is just one of the many unanswered questions surrounding Thor: Ragnarok, and some of the others are particularly intriguing...

Seeing Thor team up with The Hulk on a brutal alien world where anything goes is bound to be one of Ragnarok's many highlights, but how exactly did the green behemoth find himself in captivity on Sakaar?

During a round table discussion, the movie's production designer Dan Hennah revealed Bruce Banner's irate alter ego found his way to the planet via wormholes, which is a convenient way to make it from one end of the universe to the other, though that doesn't explain how he became one of The Grandmaster's play things.

We've already seen Valkyrie capture a hammerless Thor with a net that delivers a nasty electric shock, but surely the bulkier of the two Avengers wouldn't go down that easily. With any luck, the fans will get to see exactly how the opposition had to up its game to bag themselves a Hulk.

Ragnarok will also need to explain how Jeff Goldblum's Grand Master keeps The Hulk in captivity. No chains in the galaxy are capable of binding him for long, and given how far he can leap, escape wouldn't be an issue for the green-skinned force of chaos.

Is it possible Marvel's angry Goliath likes being on Sakaar because he's free to express his rage against beings that deserve it?
