Trivia: The song "Jailhouse Rock" is introduced by Elvis at about 1:04:40, where he talks about being in jail with "a bunch of men." And again, "these men" had a lot of fun. Then the line "No. 47 said to No. 3, you're the cutest jailbird I ever did see..." etc. So he is really describing same-sex relationships in the prison. Very ahead of his time. (01:04:40)
Trivia: Judy Tyler and her husband were both killed in a road accident on July 3, 1957, just three days after production was completed and before its premiere. Elvis Presley was so devastated by her death that he refused to watch the movie.
