Thor: Ragnarok - 10 Questions We Still Have

10. How Did The Grandmaster Capture Hulk?

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?
