The Nutty Professor (franchise)

Professor Julius Kelp is a brilliant science teacher, at a university. However, he has a problem with attracting women due to his clumsy, awkward, inarticulate nature. Women deem him as unattractive. Kelp becomes obsessed with impressing a beautiful student named Stella. With his background in chemistry, Kelp decides to develop a potion that will change him into a different person. His new suave alter ego named Buddy Love, is challenged with winning Stella's affections before his short-supply of potion is depleted.[17]

Film historians regard The Nutty Professor as the most memorable film of Lewis’ long career. In 2004, the film was selected for preservation in the National Film Registry by the Library of Congress for being "culturally, historically or aesthetically significant."[18]

Brilliant and obese scientist Sherman Klump invents a miraculous weight-loss solution. After a date with chemistry student Carla Purty goes badly, a depressed Klump tries the solution on himself. Upon taking the potion, Kelp instantly loses 250 pounds. The side effects, besides becoming physically fit include a second personality who calls himself Buddy Love and is obnoxiously self-assertive, conceited alternate personality. Buddy proves to be more popular than Sherman, but his arrogance and bad behavior quickly spiral out of control. During these series of events, Kelp must decide whether he enjoys popularity, or values self-respect.[19]

After choosing to love himself, over his popular and assertive alternate personality, Professor Sherman Klump has found love in a beautiful and kind woman named Denise. In preparations for their wedding, his undesired alter-ego named Buddy Love begins taking over. Though Klump has ceased taking his self-improving potion, Love continues to present himself and is determined to stay. After a number of appearances, Klump extracts his alternate personality's genes and decides rid the world of his pesky partner, at the risk of his own psychological decline. A laboratory incident including the accidental combination of the genes with dog hair, result in Buddy Love taking on his own existence outside of Klump's body. Unaware of the Love's new existence, the engaged couple begin to perfect a new rejuvenation formula and their fortune seems assured, until Love appears and steals it. Professor Klump's cognitive abilities continue to decline. In a final effort to defeat Buddy Love, the Professor develops a new and more potent formula that will degenerate the villain back to his state of genetic material. Using Love's canine DNA against him, he defeats him with the use of a tennis ball covered in the new potion. As Klump slips away, Denise helps him drink the genetic matter, restoring his genius intellect and resetting everything back to normal. The pair continue to prepare for their wedding, and are married.[20]

An animated legacy-sequel to the original film, the film follows the workings of Julius Kelp's grandson.

Harold Kelp is an aspiring inventor, who struggles to perfect his experiments. Intimidated by his grandfather's legacy, Harold has dreams of his failure taking the form of a giant monster. After coming into conflict with a group of angry individuals involved in one of his demonstrations, Harold decides to attend a science academy run by his grandfather, Professor Julius Kelp. Upon arriving at the school, Harold meets a beautiful woman named Polly McGreggor, with whom he becomes infatuated with. Determined to win her affection, Harold finds and takes his grandfather's secret potion. The elixir unleashes Harold's confident, self-loving alternate personality that calls himself Jack. Though initially popular with the fellow students, Jack's outrageous behavior gets out of control and causes more mischief than Harold had anticipated. Due to Harold's continued time evolving into Jack, his grades begin slipping. Learning of Harold's actions, Julius once again takes the potion to become Buddy Love. In his alternate form as Buddy Love, Julius teaches his grandson to appreciate who he is and to be comfortable in his own skin. Harold's anxieties are accidentally unleashed by one of Professor Kelp's inventions, as the visionary monster from his nightmares. Harold bravely faces his fears, and defeats the creature. In doing so, Harold says goodbye to Jack once and for all before sharing a kiss with Polly.[21]
