Turner Classic Movies' Greatest Classic Films Collection: Broadway Musicalscollects four movies on two double-sided discs, with top picture quality and the bonus features that appeared on disc 1 when one of those films was released on a two-disc set, or the features that appeared on the single discs of the other three. The four films here aren't really Broadway musicals, but rather movies that were (with one exception) based on material originally created for the Broadway stage.Show Boatwas one of the earliest shows in the modern-musical era, and this 1951 adaptation (the third, following versions in 1929 and 1936) stars familiar MGM players Kathryn Grayson, Ava Gardner, Howard Keel, and others in Jerome Kern and Oscar Hammerstein's Southern epic, featuring "Ol' Man River," "Can't Help Loving That Man of Mine," and more.Annie Get Your Gun(1950) stars Bettie Hutton (in a role intended for Judy Garland) as a spunky Western gal who gives Howard Keel all he can handle, and features such Irving Berlin standards as "There's No Business Like Show Business," "Anything You Can Do," and "Doin' What Comes Naturally."  Grayson and Keel return again inKiss Me Kate(1953), as life imitates art in a production of Shakespeare'sThe Taming of the Shrew, and the Cole Porter songs include "Wunderbar" and "So in Love."  The exception isSeven Brides for Seven Brothers(1954), one of MGM's greatest original creations that was itself adapted for the stage years later.  Keel woos Jane Powell to become his wife--and mother figure for his six brothers.  Hilarity and much dancing ensue (especially in Michael Kidd's rousing barn number), and the Gene de Paul-Johnny Mercer songs include "Bless Yore Beautiful Hide," "Wonderful Wonderful Day," and "Spring, Spring, Spring."  Bonus material on the two-sided discs is relatively plentiful for the TCM Classics series since only one of the movies had been released on a two-disc set: you loseSeven Brides for Seven Brothers' alternate cut and some supplemental material, but you still get director Stanley Donen's commentary track plus some trailers, shorts, and other material for the other three movies.--David Horiuchi
