Mickey Shaugnessy, the Irish-American character actor best known for his portrayal of Elvis Presley's musical mentor in the rock n' roll classic "Jailhouse Rock" was added to the Library of Congress' Film Registry in 2004. Sadly, Mickey Shaughnessy would not live to see that honor, nor the release of his final film. He died from lung cancer just two weeks shy of his 65th birthday on July 23, 1985.
