A person who creates films or movies, often working in the film industry.
The moviemaker spent years developing the script before filming began.
Moviemaker is formed from "movie" (from the term 'moving picture', which refers to a film) and "maker" (from Old English 'macian', meaning to make or create). The word 'moviemaker' refers to a person who creates or produces films.
Think of someone who 'makes' ('maker') 'moving pictures' ('movie') — that's why a moviemaker is a person who creates films.
