- The title is a parody of the Season 10 Doctor Who story, The Three Doctors.
- This episode marks the last appearance of the 'Phoenix Master', who 'dies' of his injuries and falls down the crater the ship made. However, at the end of the episode, his regenerated hand rises from the pit, alluding to his return, but in a different body.
- The 'Phoenix Master's death' scene is similar to the Penguin's in Batman Returns.
