Father with point about American films (7)

'films' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I don't see?

'father with point about american' is the wordplay.
'father' becomes 'patin' (I can't justify this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'point' becomes 'E' (compass point).
'about' is a charade indicator (letters next to each other).
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'e' put after 'a' is 'ae'.
'patin'+'ae' is 'PATINAE'.
