The Absent-Minded Professor
Walsh wrote and produced a series of comedies starring MacMurray and Kirk, all very popular: "The Absent-Minded Professor" (1961), a fantasy; "Bon Voyage!" (1962), an Americans-abroad family comedy, also with Corcoran; and "Son of Flubber" (1963), a sequel to "Absent Minded Professor". He provided the story for "The Misadventures of Merlin Jones" (1964), a fantasy comedy with Kirk.
