'neither section of hollywood can get over' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'point about film part' is the wordplay.
'point' becomes 'tine' (I've seen this in other clues).
'about' means one lot of letters goes inside another.
'film part' becomes 'reel' (I've seen this in another clue).
'tine' placed around 'reel' is 'TREELINE'.
