Fun fact: Eddie Murphy plays eight characters in _Nutty Professor II: The Klumps:_ Sherman Klump, Buddy Love, Mama Klump, Papa Klump, Grandma Klump, Ernie Klump, Sr., Young Papa Klump and Lance Perkins (cameo appearance). This is the most characters Eddie Murphy has played in one movie. Go figure.
It's time for Papa, Mama, Ernie and Granny Klump to throw their weight around and save the day in this laugh out loud funny sequel to the 1996 blockbuster hit
