It used to be common practice to give top billing based on a person's level of fame, regardless of the significance of their role in the film. For example, Marlon Brando received top billing in "The Godfather" (although he had less on-screen time than Al Pacino's character; Pacino was displeased that he was only nominated for the Best Supporting Actor Oscar while Brando received the Oscar nod for Best Actor in a Leading Role), "Apocalypse Now" (see above), and "Superman" (also see above). Maximilian Schell was billed fifth in "Judgment at Nuremberg" after Spencer Tracy, Burt Lancaster, Richard Widmark, and Marlene Dietrich, yet Schell went on to win the Oscar for Best Actor in a Leading Role. In recent decades, however, the practice of giving top billing to a star actor has largely been discontinued especially if they only play a bit part; some major actors may have a cameo where they are only noted within the other cast during the end credits.
