MGM has announced three westerns and two war films for release on May 12th. It's a sign of the times, I guess; this is a substantial reduction in numbers from MGM spring western and war promotions of the past. Instead, the studio has also announced a number of repackagings of past releases in various multi-packs (such as a 3-disc Cowboy Collection and a 20-disc Ultimate Westerns Collection). As there are no new titles involved and no new transfers mentioned, I'm not reporting on them in detail here. As for the five new releases, they are The King and Four Queens (1956, with Clark Gable), Doc (1971, with Stacy Keach), Young Billy Young (1969, with Robert Mitchum), Time Limit (1957, with Richard Widmark), and North West Frontier (aka Flame Over India, 1959, with Lauren Bacall and Kenneth More). MGM will also release The Good, the Bad and the Ugly (1966, with Clint Eastwood) on Blu-ray on May 12th.
Paramount continues with Hawaii Five-O delivering the Sixth Season on April 21st. April 28th brings Mission Impossible: The Sixth Season. The studio is also adding to its Centennial Collection with May 19th releases of two John Wayne westerns - El Dorado (1967) and The Man Who Shot Liberty Valance (1962). Extras on the former will be audio commentary by filmmaker Peter Bogdanovich; Ride, Boldly Ride: The Journey to El Dorado; audio commentary with critic and film historian Richard Schickel featuring actor Ed Asner and author Todd McCarthy; The Artist and the American West (1967) - vintage featurette: Behind the Gates: AC Remembers John Wayne; original theatrical trailer; and galleries. Liberty Valance will offer The Size of Legends, The Soul of Myth featurettes; audio commentary by filmmaker Peter Bogdanovich along with his archival recordings with John Ford, John Wayne, and James Stewart; selected scene commentary with intro by Dan Ford along with his archival recordings with John Ford; galleries; and the original theatrical trailer.
