And based off this following clipping from the Los Angeles Evening Citizen News, 9 Feb 1946 which suggests a 1932/1931 YOB (rather than 1933) for Jimmy Crane, I am fairly certain that he is James Justin Crane, born 4 Oct 1931 in San Francisco, died 5 Sep 1996, per Social Security Records. The day and month of the IMDB date match as does the birth place, though I can't prove the link conclusively. He is buried in Nevada: https://www.findagrave.com/memorial/102242043/james-justin-crane.
