James Dean received his second and final posthumous Oscar nomination for portraying Jett Rink in Giant.
In East of Eden his mannerisms suggested a young man uncomfortable with just about everything. Here I feel he does properly use his mannerisms this time to convey himself as a loner in the early moments most assuredly well. He is uncomfortable with his surroundings and employer. He shows a hidden sense of hatred of his character, and his hidden motives quite well. I think he is actually interesting early on, and not distracting with his little slinking in the background always. He does convey everything and more for his character of Rink, and I think his intensity and style of his performance works perfectly early on.
Later though after he becomes rich his performance changes. I do like his one scene where he announces his soon to be riches in his fantastic style. His performance though becomes very limited in terms of screen time, occasionally popping in and out very quickly. I never really believed him at all as the older rich oil man. Dean's aging was not at all convincing even though Elizabeth Taylor's and Rock Hudson's were. I thought he was slimey enough but that was about it. He was suppose to have some sort of charm I think but he doesn't and I really did not believe Dean at all as the oil man. He was perfect for Rink at the beginning but by the end he seemed to become miscast. I do not know if any other actor could have been as interesting at the beginning but I do think many could have been better than the second half of his performance.
