And as to "movie" and "film", in the use you have in mind they are effectively the same, but 'film' can have other uses ('a film of dust/dirt/grease...'). I suspect that 'movie' is preferable in Am E(?anyone?...) , and in Br E "movie" used to be regarded (and sometimes avoided) as 'American'. (I remember a rather pretentious friend in the '70s who talked about "movies"; I associated it with 'arty' films at the time, because that was the sort he used to go to.)
But today people in the UK use them interchangeably.
