I wish him well.
If he has the skill to write a script and make a film I'm thinking a nurse would be best for accuracy.
Nurses notes and ticking off on a check list is a very different skill.
It would be so good to have a realistic film. He may be the next independent film maker. Entering a film festival is a good way to get it seen. (First is getting it done.
If the film is made I will go see it.
I live in LA and know members of the writers guild. It is a unique skill set. Lots of re-writes. One uses me for nursing or medical accuracy. I do it free because I'm good friends with her aunt. If you watch TV crime fiction you've heard actors deliver her words.
I also know people with great ideas that went nowhere.
PS: That Kaiser isn't in Venice. It is near Venice Blvd. which runs west to east from the ocean past downtown LA.
California Hospital is also on Venice Blvd. Downtown LA. I've worked registry at both hospitals.
