Is their terms for the type of shot depending on if the characters in the shot, are facing diagonal, sideways, or dead on towards the camera?

But I feel something is going to be done wrong, and a more expensive movie is going to be ruined because of it.

Trusting your crew is absolutely essential to a successful project. I wouldn't want to work with a Director who didn't trust me, or alternately who I didn't trust.

If you're not confident in your crew's abilities, find new crew.
