Avengers: Infinity War - 12 Behind-The-Scenes Secrets You Need To Know

9. Peter Dinklage's Hair Clue

It has FINALLY been confirmed that Peter Dinklage is involved in Infinity War after almost a year of empty speculation in the wake of reports that he had spoken to Marvel about a part.

We still don't know who he's playing, but it's important to remember that there WAS a hint a while back that could fit in with what we now know about Nidavellir.

A year or so ago, the Daily Mail posted some images of Dinklage in a salon in Manhattan where he appears to have had his hair dyed red right around the time he was apparently filming Infinity War. At the time that fit with rumours he might be playing Pip the Troll, but it's much more likely that he's playing another Marvel redhead - Eitri, the King Of The Dwarves.

So, in other words, we might well be seeing him revealing the Thor the genesis of the Infinity Gauntlet and giving him Stormbreaker.
