I'm searching for a hook in Drupal 8 API for adding values to a add content form. What hook can I use to alter values from /node/add/movies_movie page?

Inside your module, there is a [your-module].module file where you can write hook_form_alter()
.
/**
* Implements hook_form_alter().
*/
function module_name_form_alter(&$form, FormStateInterface $form_state, $form_id) {
if ($form_id == 'node_movies_movie_form') {
// Your code goes here.
...
...
}
}

And of course don't forget to clear cache after implementing
hook_form_alter()
