Better Explanation: Disney has recently been reusing actors and actresses from their Marvel brand in their live-action movies.
Hayley Atwell (Agent Carter) was Cinderella's mother in Disney's Cinderella, that was released in 2015
Black Widow (Scarlett Johansson) is Kaa in Disney's The Jungle Book, that will be releasing to movie theaters on April 15, 2016
Maybe the Marvel Cinematic Universe is also connected to the Star Wars universe as well, since in Star Wars Episode 3: Revenge of the Sith, Darth Sidious shocked Mace Windu (Samuel L Jackson) in the eye with force lightning before throwing him out the window in the Jedi Temple on Coruscant, which can easily explain why Nick Fury has the eye patch in the Marvel Cinematic Universe, since they are played by the same actor.
