[Difficult to ask this questions without spoiling parts of the plot, read with caution]
I recently saw Guardians of the Galaxy Vol. 2, and I am confused regarding Ego's face (I watched the film in English which isn't my first language).
During the scene where Ego tells Quill that he can chose any appearance that he wants, he quickly morphs into David Hasselhoff, referencing a scene in which Quill says he pretended Hasselhoff was his father. This indicates that a lot of U.S. pop culture elements exist in the world of GotG. However, we see him throughout most of the film, including in the first scene that takes place in 1980, "wearing" Kurt Russell's face. However, in the 1980s, Kurt Russell was already a famous actor, since he started acting in the 1960s. In 1980, when Ego came to impregnate a human, he didn't know back then that his son would love U.S. pop culture and that looking like Kurt Russell would help his get his son on his side.
Did Ego model his appearance on American actor Kurt Russell's face, or is his face supposed to be the face of an unknown person?
