Douglas Fairbanks shines in a swordplay-filled double bill. First, foppish Don Diego (Fairbanks) dons cape and mask to protect the peasants of Old California as the dashing "Zorro, the Fox." Noah Beery, Marguerite de la Motte also star in "The Mark of Zorro," the standard-setter for all subsequent screen swashbucklers. Then, Fairbanks essays four roles in the classic, thrill-packed sequel, "Don Q, Son of Zorro," including both the title role of the irrepressible son, Cesar de Vega, and of his legendary father. With Mary Astor, Donald Crisp and Warner Oland; directed by Crisp. 3 2/3 hrs. total. Standard; Soundtrack: Dolby Digital stereo music score; home movies; more. Silent with music score.
