It is the sequel to the 1963 live-action Jerry Lewis comedy of the same name and based on the story Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson.

He is frequently attacked in his visions by his fear, which takes the form of a group of burly dodgeball players as well as a black monster.

After encountering an angry mob involved in his bad inventions, Harold is informed by his robot assistant, Robin that he will be sent away to a science academy where his grandfather, Julius Kelp has taken up a duty as Professor.

While under his Buddy Love alias, Julius compares Harold's School life to a 63 Cutlass Supreme, the 63 is a reference to the year 1963 in which the original film was released.

The film is less about facing fear than being overwhelmed by terrifying situations -- stick to the original if you're looking for a good movie for kids.
