Idris Elba would like to reprise the role of Heimdall in the Avengers: Infinity War at the hands of Thanos (Josh Brolin).
Unlike those who perished as part of the Mad Titan's ruthless snap, Heimdall, like Loki (Tom Hiddleston), Vision (Paul Bettany), and Gamora (Zoe Saldana) remained dead following the events of Avengers: Endgame. However, Elba is the only one from that roster that doesn't have an appearance in the MCU, with all the other supposed dead coming back one way or another. Despite this, Elba is optimistic that he'll have the chance to step into the shoes of the all-seeing, all-hearing Asgardian sentry again in the future.
Speaking with Fast & Furious Presents: Hobbs & Shaw, Elba was asked about his MCU contention. itting that he's yet to see Endgame, and warning everyone to not spoil anything, he discussed what his future is as Heimdall. While there's no concrete plans, he's open to reprising the character again.
Listen, Heimdall is essentially part of the god family. So you know, he essentially could be alive. I’m just saying! I’m just putting it out there! The Heimdall character goes way back into, you know, the Thor mythology…And I’m sure there will be an interesting way to bring that alive. Of course I would. Yes.
Elba isn't wrong, considering Heimdall's origins, there's a string of ways he can be brought back into the MCU. If they don't want to overcomplicate things or be accused of faking deaths again, Marvel Studios can explore earlier timelines when Heimdall was still genuinely alive. The Thor: Love and Thunder, bringing back Elba, who's more than willing, wouldn't be that difficult.
In the event, however, that Heimdall's journey in the MCU is done, comic book fans can still look forward to Elbda playing a different role at DC. The Suicide Squad, slated to come out in 2021. Perhaps once that's out and Marvel Studios realizes how big of an opportunity they missed by not fully utilizing Elba and Heimdall, they'll think of a way to bring him back.
