He was nuts, but he was a brilliant actor. He changed film acting. His string of performances in the early 1950s was extraordinary:
- The Men in 1950
- A Streetcar Named Desire in 1951
- Viva Zapata! in 1952
- Julius Caesar in 1953
- The Wild One in 1953
- On the Waterfront in 1954
Fifty years later his work is still stunning. It's too bad he spent the last thirty years working so infrequently. If he was actually happier by working less I wouldn't have minded, but his life was perhaps even more chaotic in his later years. There may never be another actor who has the kind of impact he did on acting.
Simply put, in film acting, there is before Brando, and there is after Brando. And they are like different worlds.
