Fred MacMurray stars in this double-feature of two of Disney's most popular      live-action comedies from the 1960's. The Absent Minded Professor          (Robert Stevenson, USA, 1961, 97 mins.) has the actor portraying Professor Ned   Brainard, the inventor of flying rubber (or "flubber"), a substance capable of giving items and incredibly energetic bounce. Unfortunately, the professor     finds no buyers, although one corrupt businessman (Keenan Wynn) is quite       interested in stealing it. The sequel, Son of Flubber (Robert Stevenson  , USA, 1963, 100 mins.), has the harried professor fending off huge IRS tax      bills for the invention, although he and the college have not made a cent from flubber and the substance is deemed top secret by The Pentagon. Can his newly  invented "flubbergas" solve his problems?                                        Robert Stevenson---USA---1961/1963---197 mins.
