   </div>
</div>

// Genres value is : anime, action, adventure,

function post_creation() {
    if(isset($_POST['movie_nonce_field']) && wp_verify_nonce($_POST['movie_nonce_field'], 'movie_nonce')) {
        if(strlen(trim($_POST['title'])) < 1 || strlen(trim($_POST['overview'])) < 1) {
            $redirect = add_query_arg('post', 'failed', home_url($_POST['_wp_http_referer']));
        } else {

            $category = array( $_POST['genres'] );

            $post_info = array(
                'post_type' => 'movies',
                'post_status' => 'pending',
                'post_title' => esc_attr(strip_tags($_POST['title'])),
                'post_content' => esc_attr(strip_tags($_POST['overview'])),
                'post_category' => $category,

            );
            $post_id = wp_insert_post($post_info);

            if($post_id) {
                update_post_meta($post_id, 'ecpt_postedby', esc_attr(strip_tags($_POST['user_name'])));
                update_post_meta($post_id, 'ecpt_posteremail', esc_attr(strip_tags($_POST['user_email'])));
                update_post_meta($post_id, 'ecpt_contactemail', esc_attr(strip_tags($_POST['inquiry_email'])));
                $redirect = add_query_arg('post', 'successfull', home_url($_POST['_wp_http_referer']));
            }
        }
        wp_redirect($redirect); exit;
    }
}
add_action('init', 'post_creation');

Categories not save to post.

I want to add new post to categories if it already exist And create new category if it doesn't exist

It looks like you're trying to use the default Post post type's Category taxonomy with your custom post type movies.

$post_info = array(
  'post_type'     => 'movies', // custom post type here
  'post_status'   => 'pending',
  'post_title'    => esc_attr(strip_tags($_POST['title'])),
  'post_content'  => esc_attr(strip_tags($_POST['overview'])),
  'post_category' => $category, // categories are by default only for Post post type
);

Have you already added such code to your site, which allows you to use the default Category taxonomy with your custom post type? If not, have a look here on how to do it, tags & categories with custom post type

If you have registered a custom taxonomy for your movies post type, then you should use tax_input in your $post_info array. Like so,

$post_info = array(
  'post_type'     => 'movies',
  'post_status'   => 'pending',
  'post_title'    => esc_attr(strip_tags($_POST['title'])),
  'post_content'  => esc_attr(strip_tags($_POST['overview'])),
  'tax_input'     => array(
    'some_custom_taxonomy' => $category
  ),
);
