- Keep the script open to your cast
I'm already learning from this for the sequel: my draft is completely open to my cast/crew (which is composed of like three people besides myself right now), and I've talked with them about different technical and story-based details, providing an update whenever there's a significant change or solution to a problem. Note to future me: I am not Ridley Scott. I am not at the level where I can make such artistic decisions and have them work. And I've actually never seen Alien so I'm pretty sure taking inspiration from it is a bad idea until whenever I do so.
- Be open to suggestions
The takeaway: as the amateur director, the movie's image may mainly be yours, but if your crew think a scene really lacks humanity or isn't enjoyable, odds are that the audience may think the same thing.
- Lighten the script up a bit
- Look up how stuff's pronounced
- If you're doing something cool by sliding your hands across the blade of a knife, please don't actually grab the blade hard or at all
