After seeing the newest casting for Deadpool, I'm even more curious about how the MCU will handle Deadpool going forward, and whether the actor will remain in the role permanently now his version of the character has been added into the Marvel movie worlds' multiverse. Despite first appearing as a decidedly less popular version of Deadpool in X-Men Wolverine: Origins, Ryan Reynolds went on to play a more comic-accurate version of the character throughout Deadpool's own movie trilogy, which came to define the antihero in a major way.
