Cain has a clear, politically conservative view on the immigration question. However, he doesn’t take issue with Gunn’s premise. He accepts that Superman is an immigrant. However, he feels the fact that the director made the statement publicly has the potential to hurt the movie. Cain said…

The former Superman takes issue with the director's comments about the new movie being an immigration allegory: "We know Superman is an immigrant — he's a freaking alien."

In an interview with TMZ, Cain expressed concern that the upcoming movie had lost the values he associated with the character, particularly “truth, justice, and the American way.” This is only one of the many versions of the superhero’s slogan, which has not always included “the American way.”
