actors normally steal scenes from their co stars. With Marlon Brando, it was different. He stole entire movies from his co stars. there are numerous examples which i have to offer. His on screen time is less compared to others, but you come out of movie remembering only Brando.

The most famous are:

A Streetcar Named Desire: It was a tale about Blanche - the protagonist but Brando as the antagonist (in a much smaller role as far as screen time was concerned), got the audiences attention and in fact so overpowering was his personality, that despite on of the all time great performances by Leigh as Blanche, the audiences were rooting for Brando.

The Godfather: He was Vito, but al pacino as michael had the longer role, but Brando with only 45 minutes of screen time makes his presence felt so vividly, that even when he is not on screen, you can feel his presence and him guiding the proceedings.

Apocalypse Now: Same reasoning as the Godfather, but here Brando with only 15 minutes of screen time so totally dominates the proceedings, that you feel his aura is pulling the boat to him. from his voice played on the recorder when sheen is getting his briefing, to the photographs that sheen has of Brando in his dossier. Everything is Brando.

Julius Caesar: He is Marc Antony, not the central figure but who delivers one of the greatest speeches ever written better than it has even been delivered. James Mason as Brutus has the longer role, but it's Brando all the way.

The Score: Brando in his last screen appearance, against Deniro and Norton, steals this utterly butterly deliciously...

How this man was able to so dominate the frame that his being off the screen would make the movie seem lesser and him being on screen would raise it to even greater heights.
