I was in an Art History class, and this was the final comment in one of the recent lectures. Are there points of unity between these 2? They were both in their prime at about the same time, the mid to late 1940's to the mid fifties. They both were from the inner part of the US. Both their styles relied on improvisation from form, Jackson with his painting style and Brando with his ability to slide around the dialog specified in the script. Both also, in there personalities, represent a masculine irrationality in there work and in their personal lives.
