Nutty Professor II: The Klumps (DvD) starring Eddie Murphy & Janet Jackson.
Everything is coming up roses for Professor Sherman Klump (Eddie Murphy). His fiancée, the equally brilliant Denise Gaines (pop music star Janet Jackson), loves him for his prodigious mind. Sherman's university has just been offered $150,000,000 for the radical new youth serum Sherman has developed. And the big-eating, trash-talking Klump clan (all played by Murphy) couldn't be happier. The only person who can ruin things now is Sherman's nemesis: his idlike alter ego, the smooth-talking, flashy dressing Buddy Love (also played by Murphy). In an attempt to destroy Buddy once and for all, Sherman manages to locate and extract the DNA strand that represents the last remaining trace of his own private Mr. Hyde. But the gene accidentally mutates with a strand of dog hair, giving birth to a brave new Buddy who sniffs out the Klumps. With the help of Academy Award-winning makeup wizard Rick Baker, Murphy magically disappears into multiple roles for uproarious results. NUTTY PROFESSOR II is a hilarious sequel to the 1996 remake.
