A good opening and a good ending make for a good film provide they come close together.
I like doing them and they're ridiculous and the actors can improvise a lot, and they don't have to be really realistic characters that hit a very specific tone as in a feature film. They're really fun, I want to make more of them definitely.
It's the first villain that I've played in a movie that has absolutely no vulnerability and no innocence, nothing whatsoever that is likeable about her other than she's so bad.
