How do tu make a movie without actors?

Claymation
Stopmotion
A puppet show?
One of those LEGO animations?

If you're willing to practice, tu could do a silent animated film (much like the oldest disney shorts)

why would tu want to do that. is your brain in a penalty box?

Secretly film people.

tu can make a documentary where none of the people are actors

Well, tu need actors to make a film, no matter what kind, otherwise, there would be no story and the fact that tu suck at animación makes the situation harder. My suggestion, make a film about ghosts. tu don't need any actors and still make some action happen por moving the props.

film without an actor of course does not mean anything. actors that make up the content of a film. maybe tu can ask for your friends to help you. Success

tu can try doing it all yourself then animating what tu did on a computer o something. But that'll be really hard...

impossible

Learn to spell, this would be a great advantage as no one will take tu seriously if tu can not even put a centaencea together, see what I mean.
