Metro-Goldwyn-Mayer celebrated its 50th anniversary with That’s Entertainment!, an outstanding, stunning, sentimental, exciting, colorful, enjoyable, spirit-lifting, tuneful, youthful, invigorating, zesty, respectful, dazzling, and richly satisfying feature documentary commemorating its filmusicals.As Liza Minnelli puts it in her narrated segment (among 11 names appearing in new footage and film clip voiceover). ‘Thank God for film. It can capture and hold a performance forever’. From the musical library, about 100 films were selected from the 1929-58 era, enough to satisfy nearly every memory. Each segment has a particular theme (usually film highlights of a particular star); and each has its narrator. Minnelli appears in the portion devoted to her mother, Judy Garland.
