What are the biggest mistakes which you can make when you write a screenplay? Often, I hear it’s something simple like camera advices. But there must be more than this. Do you know some?
Telling instead of showing. Film is visual. Rather than using long segments of dialogue to explain something, you should show it if at all possible.
@El Director Show in a script. how do you do that?
That's also called "on the nose" dialog.
So there's my contribution.
Writing on the nose is a screenwriting term that refers to dialogue or action in which the character's innermost thoughts and feelings are fully expressed by what the character is saying or doing. There is no nuance, mystery, ambiguity or surprise (as there is in real life).
