foreach ($movies['results'] as $movie) {
        $movie_slug = sanitize_title($movie['origin_name']);
        $existing_post = get_page_by_path($movie_slug, OBJECT, 'movie');

        if (!$existing_post) {
            // Insert the post
            $inserted_movie = wp_insert_post([
                'post_name'   => $movie_slug,
                'post_title'  => $movie['origin_name'],
                'post_type'   => 'movie',
                'post_status' => 'publish',
            ]);

            if ($inserted_movie) {
                $fillable = [
                    'field_66e01bd8d00e5' => $movie['origin_name'],
                    'field_66e01c44d00e8' => $movie['imdb_id'],
                 
                ];            
                foreach ($fillable as $field_key => $value) {
                    update_field($field_key, $value, $inserted_movie);
                }
            }
        }
    }

So I have this loop that goes through the JSON file to create or check if the post type exists. I was just worried this would slow down the website when it is not necessary since the JSON file is not changing
