Sylvester Stallone
The year is 1978, a very different Superman: The Movie would have been shown in the cinemas if Sly who "lobbied hard" for the role got it.
Too bad for "Rocky" the Godfather himself, Marlon Brando, landed the role of Jor-El. Brando had casting approval for the role of Superman, and he did not approve of Sly. Even the producer of the movie had a hard time imagining Stallone for the role.
