Good morning, Haggs Hacker.
I've just seen your post, so apologies for the delay.
No doubt you have 19ac. by now, but just in case.....
It's a straight definition clue - the answer is originally French for someone who takes an artistic interest in films / the CINEma - although I've only heard it used as a synonym for someone who makes films.
Hoping this helps!
