Twentieth Century Fox Home Entertainment keeps coming up with beautifully produced box sets drawn from their extensive library, and today’s release of “The Tyrone Power Matinee Idol Collection” is no exception. There aren’t any major discoveries among the ten (!) impeccably transferred titles, although there is a minor one: “I’ll Never Forget You,” Roy Ward Baker’s oddball, 1951 remake of “Berkeley Square” with an injection of atom age anxiety (and its long unavailable Technicolor sequences restored). Most of the set concentrates on the kind of bread-and-butter star vehicles that constituted the greater part of any studio’s production during the classical era, and it is fascinating to see the evidence for a Fox “house style” that emerges from minor efforts like Edward H. Griffith’s “Cafe Metropole” (failed Lubitsch) and Tay Garnett’s “Love Is News” (failed Hawks). But constant throughout are the huge, carefully detailed sets and the distinctively wide tonal range of the cinematography, which ranges from inky blacks (the sort carefully avoided by MGM and Paramount) to celestial whites (every time Power uncorks that smile).
