I think prequels were created because the original story came to an end, but it was a commercial success.....so prequels were invented.....it's funny because chronologically the prequel comes first, the "original" film second, and the sequel last!

sequel

A sequel.

The opposite of prequel is sequel. Prequel is before something and sequel is after something. prequel(noun) In a series of works, an installment that is set chronologically before its predecessor, especially the original narrative or (perhaps improper usage) any narrative work with at least one sequel. sequel (noun) something that follows something else
