Idris Elba figures they can probably bring him back for Thor 4 somehow, right?

Idris Elba has not had an especially great time during his tenure in the Marvel Cinematic Universe; despite being a talented and charismatic actor, he got saddled early on with playing one of the dullest characters in one of the (until recently) dullest sub-franchises of the Disney mega-giant, a.k.a. Heimdall, a.k.a. Stoic Sword Man What Glares At Folk. The first two Thor movies did not help those Elba satisfaction levels—he’s talked in the past about the despair he felt while doing reshoots on the second one, called back to be covered in fake hair and hold a fake sword on a soundstage just days after embodying Nelson Mandela for 2014's Long Walk To Freedom. Even in the fun one, he gets stuck with one of the most boring parts, playing a game of Metal Gear Asgard while Cate Blanchett devours Valhalla one speech at a time. And then along came Infinity War, where Elba doesn’t even get his own heroic sacrifice, instead serving as a “No, seriously, we’re killing characters this time” apertif for Thanos’ murder of Loki. It’s enough to put a guy off playing strong, silent, boring types for good.
