Idris Elba is a familiar face in the Marvel Cinematic Universe, but he does wish his role was much bigger.
That all said, there is no doubt that Elba could be the superhero he desires, it just may not happen in the MCU.
I like what I have, but I also wish that I had a bigger character in the Marvel universe…
Should it happen, there is little reason to believe Elba couldn’t handle it, but for now we’ll have to see what his future holds in the MCU as Heimdall.
