…translates to “The Wild Planet” (1973) directed by René Laloux (Paris, France)
“This futuristic story takes place on a faraway planet where blue giants rule (Draags), and oppressed humanoids (Oms) rebel against the machine-like leaders.”

Note: Some scenes feel like Salvador Dali paintings coming to life.
I recommend watching it in the dark so you can fully immerse yourself in it.
