From the new bio on director Nicholas Ray ("Rebel Without a Cause," "Johnny Guitar"), quoting Ray on actor James Dean:
"The drama of his life was the drama of desiring to belong, and fearing to belong... It was a conflict of violent eagerness and mistrust, created very young... The intensity of his desires, and his fears, could make the search at times arrogant, egocentric; but behind it was such a desperate vulnerability that one was moved, even frightened. Probably, when he was cruel or faithless, he thought he was paying off an old score. The affection he rejected was the affection that had once been his and found no answer."
