Answer
Marlon Brando was paid $4 million and a percentage of the profits for playing Jor-El for 12 shooting days, which yielded 10 screen minutes in the film 'Superman'. The fee (plus the percentage) also covered the sequel, which was being simultaneously shot with the original. Brando did not appear in the sequel, however, as he was involved in a lawsuit with Ilya Salkind over what Brando said was the producer's non-payment of his profit-participation for this film.
