Avengers: Infinity War - 10 Things Marvel Don't Want You To Know

9. Peter Dinklage's Cameo

The Spoiler:

Game Of Thrones star Peter Dinklage has a role in Infinity War, which is thusfar secret as Marvel have been careful to leave him out of all marketing materials.

Given the other evidence, he's most likely to be playing the Dwarf who forges Jarnbjorn for Thor.

The Evidence:

Way back in January 2017, whispers of Dinklage being in talks with Marvel for a role surfaced. At that point he was linked with playing Pip the Troll (as Adam Warlock was expected to debut), or MODOK - basically any character who suited his stature.

But with LEGO seemingly confirming Nidavellir, you'd have to put money on him appearing there.
