Now, I can definitely understand why hardly anyone's a fan of the short list of actors for Captain America. I'm downright confuzzled by it too. But then I remembered something.
Remember back when they were casting Thor? There was also a "short list" of contendors for the role, including Tom Hiddleston (who was cast instead as Loki), some dude named Joel Kinnaman, Charlie Hunnam, and Liam Hemsworth. While Alexander Skarsgard was the fan favorite, eventually, the producers went left field, and cast (ta-da!) Liam's brother, Chris!
When thinking in this context, it's not going to really shock me if that "short list" was a ploy, or not even the full thing. Hell, it's pretty likely Johnston and the execs will pull a similar move like Brannagh and the Thor movie producers did and cast someone fairly left field as well.
This is especially supported by the fact that they are allegedly looking to cast an unknown.
So don't worry, good CBMers! We've still got some time until our guy's announced!
Just please don't cast John Krasinski. I love him in The Office, but superhero he is not! (desperately prays)
