Craig Slocum is mentioned in the James Dean Story, by Ronald Martinetti, a biography on actor James Dean's life. Already a legend in his lifetime, Dean became a cult hero in his death. Craig hung out with him when he was 18 years old and was part of his circle. It was a crowd he later cryptically, or maybe not so cryptically, described as "Jimmy's little girlfriends and boyfriends." He is mentioned as Rusty Slocum in the Debts and Acknowledgments section, and Index.
Slocum is quoted as saying, "He had a vital gift for bringing people into their own focus."
"When you were with Jimmy, he could make you feel like you were the one person in his life."
Craig was known to his friends as Rusty because of his red hair. People who have contacted me, who knew Craig personally, said when they knew him, it was always as Rusty. That's a good nickname for him!
