Flubber

Professor Phillip Brainard (Robin Williams) creates a sentient green goo that enables objects to fly through the air, known as Flubber. With the help of his robot assistant Weebo (Jodi Benson), Brainard tries to prove Flubber's worth and win back his fiancée, college president Sara Jean Reynolds (Marcia Gay Harden). Along the way, he must also thwart the plans of his rival Wilson Croft (Christopher McDonald) and Medfield College sponsor Chester Hoenicker (Raymond J. Barry).
