Buzz Lightyear of Star Command: The Adventure Begins
What they share
Both films are directed by Tad Stones, and they sit in Action / Animation / Science Fiction / TV Movie territory. If that's the register that drew you to Hellboy Animated: Blood and Iron, the second film will land in a comparable space — through a different lens.
What Buzz Lightyear of Star Command: The Adventure Begins is
Buzz Lightyear apparently needs backup. He battles Emperor Zurg with three wannabe partners. It manages to launch a franchise.
