Drama, Historical, Musicals, Comedies (romantic, spoofs, slapstick), Westerns, War movies, Sci-fiction horror etc. A 60 year career, with 40 movies, 1 Television performance, about half a dozen theatre productions - so he had less than 50 outings to play just about every character in every possible genre.

He had his greatest success in dramas and which resulted in Brando redefining screen acting for ever. But he had gems in nearly every other genre which are the works of a genius
Have listed down my favourite movie from each genre.
Drama - On the Waterfront / The godfather. (depends on which side of the bed i get up from)
Historical - Mutiny on the Bounty (it really gets on my nerves that it gets unjustly criticized)
Musicals - Guys and Dolls (the only one he did, great one at that)
Comedies - The freshman (have already raved about it on every occasion possible)
Westerns - One Eyed Jacks (this movie hits u in the gut, always)
War movies - The young lions (vastly underrated classic despite being a huge hit)
Sci-fiction horror - The island of Dr. Moreau (probably his worst film ever).

SO Marlon Brando did it all, and did it his own way, and that way has never been traveled upon again by anyone...

Brando defined versatility and how - 1953, the year of the first cult bike movie and also the year of Marc Antony.

The same year Brando portrayed a rebel bike leader - Johnny Strabler in the Wild One and also Marc Antony in Julius Caesar. Which other actor - male female animal robot can boast of that. Not only was he brilliant in both, he created characters which have become synonymous with rebellion and as well for opening doors for American actors who want to tackle Shakespeare.

Who can forget - Brando's retort to the query - what you rebelling against? The rejoinder is a part of pop culture - Whattya Got!!

Who can forget a sexy Anotny who comes into his own and steals the movie from stalwarts like James Mason, john Gielgud when recites the famous - Friends Romans Countrymen. Never was Shakespeare more dynamic and vibrant.

That was the magic of Brando, the king of actors, no matter what the character was.

Marlon Brando never trusted himself with comedy, and yet was very good at it. Besides the great heavy dramatic parts he is most famous for, there is only 1 comic performance for which he won rave reviews _ the freshman. a work of pure genius.

Brando and his comic movies:
The teahouse of the august moon - a delightful romp in post war Japan, where Brando plays a Japanese interpreter who hoodwinks the US army captain, played by Glen Ford. Brando is very good at it and excels in the physical comedy. His body language is very good and the most important thing called timing, he has in plenty. The opening and closing monologues played directly to the camera are hilarious. A must watch and a huge hit when it was released.

Bedtime story - Brando is again in good form, in a movie which has unfairly been criticized.
Candy - a disaster of a movie has Brando and the rest of the cast hamming away.
The countess of Hong Kong - a movie 30 years too late, this would have been very successful had it released in the 30s. Brando has his moments, but the film as a whole just does not take off. Of course there are scenes where Brando is genuinely funny when he is figuring out where to hide Sophia Loren in his cabin and there is incessant knocking on the door.
The freshman - a brilliant movie and a great performance. already have a post on it.
Don Juan Demarco - good solid film and Brando is in good form and has amazing sexual chemistry with Faye Dunaway, the high point Brando and Depp enjoying playing of against each other..
Free Money - a bad film, with Brando having fun and that’s about it.

Besides these Brando has given performances where he has indulged in comedy even though the genre of the movie may be different: Guys and Dolls - great film and the anti western Missouri Breaks, where he gave a twist to his character and played him as a sadistic hit man who has his quirks which resulted in the comic elements. Suffice to say that Brando was mesmerizing in this film.

SO the man had it all, and he did it all.
