Marlon was already one of the biggest names in Hollywood's Classical Films era. He top-billed unforgettable movies such as A Streetcar Named Desire (1951), Viva Zapata (1972), and On the Waterfront (1954), where he won his first Best Actor Oscar.
In the latter part of his career, Marlon Brando gained another distinction to become the highest-paid actor in a cameo role. The Guinness Book of World Records reported that he was paid $3.7M ($16M in today's dollar) up front, plus a hefty percentage on the gross earning of the mega hit film Superman, all for a mere 13-days of work.
