Elvis Presley would have been 75 this year. That's the excuse that Warner Home Video, NCM Fathom and Elvis Presley Enterprises have mustered to bring "Elvis on Tour: 75th Anniversary Celebration" into theaters on July 29, at 7 p.m. This event centers on footage from the 1972 Golden Globe Best Documentary "Elvis on Tour." But the event's promoters say it will also include never-before-seen material and a new retrospective from Priscilla Presley, as well as fresh compilations produced by Martin Scorsese to cover Elvis' early concert and movie career. (The still at left is from Presley's 1973 "Aloha from Hawaii" TV special.) "Elvis on Tour Redux" is set for a handful of area theaters, including the AMC multiplexes in Owings Mill and Columbia and Cinemark Egyptian 24. Was "Elvis on Tour" your favorite Presley concert film? What about his 1968 TV sensation "Elvis" or the 1970 documentary "Elvis: That's the Way It Is?" And which Elvis features will Scorsese draw on? I'm betting on Richard Thorpe's "Jailhouse Rock," Don Siegel's "Flaming Star" and Philip Dunne's "Wild in the Country" (from a Clifford Odets script!).
