...Yes, this is definitely a film-themed puzzle.
Loved the clue for POW! (it stands for Puzzle Of the Week if anyone's curious). So I guess his favorite clue would be a COW? Doesn't sound as awesome.
And on today's episode of "me overthinking clues", I was thinking "Warmer?" at 6D would be something that warms, like a BOILER maybe (I had the final ER filled in when I saw the clue).
