If you are seeking a word only in relation to movies, then cinephile would be the perfect term. Your phrase would then be along the lines:

The definition from Oxford Languages online is as follows.

a person who is fond of the cinema.

However, if you are seeking a more generic word to describe someone who enjoys something, then you have a great many choices, some of which have already been offered by others (e.g. connoisseur, fan, etc).
