Heimdall

Aside from the fact that he hasn’t really seen much action, there’s a glaring reason why it’s disappointing that Heimdall has been underused in the Marvel Cinematic Universe – Idris Elba. Elba is an awesome actor and it’s really disappointing to have seen him cast as Heimdall, only to play a relatively small role in the franchise (granted, Elba might not care, as he has openly stated he doesn’t like the role, but that’s another matter).

Although he has appeared in three movies – Thor, Thor: The Dark World and Avengers: Age of Ultron (albeit as an illusion in the latter) – he hasn’t done much more than advise Thor on tactics and the whereabouts of Jane Foster as he gazes into the cosmos.

In Thor: The Dark World, he did take down a Dark Elf ship on his own – but that just shows audiences what they’re missing when he’s standing around not doing much fighting, which is what he’s doing most of the time.

The mythological version of the character (known as Heimdallr) and Loki are foretold to kill each other during the Ragnarok event, so it sounds like he could have a bigger part in the upcoming Thor movie based on it.
