The Museum of Television & Radio has uncovered a pair of gems two episodes of The Lloyd Bridges Show, the Sea Hunt star's 1962-63 CBS anthology series, directed by indie-film pioneer John Cassavetes. ''A Pair of Boots'' and ''My Daddy Can Lick Your Daddy'' will air back-to-back on TV Land July 20 from 7 to 8 p.m. and July 22 from 6 to 7 p.m. ''Boots'' casts Bridges as a Civil War rebel whose truce with Union troops threatens to break down over one Southern soldier's desire to reclaim a pair of shoes stolen by a Yankee. In ''Daddy,'' penned by Chinatown screenwriter Robert Towne, Bridges plays an aging boxer fighting a match against his own grown son. Though these episodes don't foreshadow Cassavetes' improvisatory filmmaking style, they do burn with the same emotional intensity found in such later big-screen works as A Woman Under the Influence. ''Boots'' also features two notable supporting actors Lloyd's son Beau and future Cassavetes cohort Seymour Cassel. Perhaps most surprising of all, the innovative Lloyd Bridges Show was created and executive-produced by Mr. Melrose Place, Aaron Spelling.
