Actually, I met a lot of directors and most of them have that fantasy to make a silent movie because for directors it's the purest way to tell a story. It's about creating images that tell a story and you don't need dialogue for that.
It's about storytelling. The story is told through images. So with the cast, I had to make sure that the emotions were readable without sound... I know some great actors, if you turn off the sound, you don't really know what they're saying
This is the problem with language, and this is what makes silent movies fun, because the connection with them, me or the audience is not with the language. There's no question of interpretation of what we are saying it's just about feeling. You create your own story
If you try to make a silent movie with a normal script and you just pull out the dialogue, you will have big problems with the actors because you will ask them to tell a story that you don't know.
When you do not have the dialogue to explain things, you will use everything to show and to tell the story. I think that this is what makes you believe that it is impeccable
