The motion tracker Spike uses is a direct nod to the Alien movies
Unlike most episodes, this episode doesn't end with "See you Space Cowboy." Instead, the text simply reads "The End," making Ed's comments in the next episode preview even funnier.
In the scene where Spike is on Bebop's bridge some of the classic Star Trek (1966) bridge sound effects (the beeps and twangs) can be heard in the background.
The Japanese title of this episode is different from the English title of "Toys in the Attic". The Japanese title is "Yamiyo no Heavy Rock" or "Dark Night of Heavy Rock".
