The Winter Soldier is the younger Luke Skywalker
This media is contrasting the faces of Mark Hamill, who is the actor who plays Luke Skywalker, in the Star Wars movie series, and that of Sebastin Stan's superimposed on Mark Hamill's head. It goes on to explain that Disney owns both Star Wars and Marvel, and implies that there must be a conspiracy, because the two faces look very similar. Mark looks young, and Sebastin Stan looks very similar but just a little bit older and has some facial hair. They look very similar and it is hard to tell that they are two different people.
