I am watching something, and the actor taps their thumbs - bored, or impatient. I thought - that's showing us [internal state], rather than telling us through thought or monolog / dialog. Unless actors constantly do voice overs - which for a multi character scene would be kinda weird - then the screen play (showing my complete lack of experience in nomenclature here) would be all about showing, rather than telling yeah? Do you think it would be worthwhile to write (a) script / screenplay to get used to describing character movement and facial expression and non-verbal communication where it's almost a necessity. Realising rules should be understood, not religiously adhered to. But for the experience / skill development?
