Kenny gets a Sony PSP in this episode, despite him being poor. This could be because he won the $523,000 lawsuit in "Cartmanland" or a no payment for two years deal, as Cartman mentioned in "Poor and Stupid".
After Satan is defeated, he turns on his adviser, who resembles (especially given the other references in this episode) Gríma Wormtongue from The Lord of the Rings but wears a black cloak more in keeping with Darth Sidious from Star Wars. His appearance also arguably resembles General Klytus from the 1980 film Flash Gordon and the Devil's portrayal in the Mel Gibson directed film The Passion of The Christ. Satan refers to him by name as Kevin, and zaps him. The advisor could also be considered to be a parody of Desaad, Darkseid's advisor. (This character later appears again in "Hell on Earth 2006".)
A Lord of the Rings reference in the episode includes the orb used by Satan, a reference to the palantír held by Saruman, the gates of Heaven being deliberately designed to look like Minas Tirith and Satan's minions are reminiscent of the Orcs and Uruk-hai from the movies. The council of the Angels is also a reference to Council of Elrond in The Lord of the Rings. Also, during his description of the battle, Archangel Michael comments that the battle is "ten times bigger" than the one in The Lord of the Rings movie, referring to the CGI battles in the film trilogy. The armies of Heaven and Hell are clearly modeled after those in the final battle in the series.
There are many references to Monty Python and the Holy Grail in the episode. When Kenny is at the gate of Heaven, a Pythonesque "Open the gate!" is heard - this is also said by King Arthur in the film. Moreover, Heaven's army celebrates winning the war by cheering in a manner not unlike the similar moment of "much rejoicing" in the film's animation segments of Terry Gilliam.
The references to Keanu Reeves throughout the episode are based on Reeves' regular appearances as savior type characters, upon whom the triumph of good over evil depends, in films like The Matrix, Constantine, and The Devil's Advocate. The greatest similarity to Keanu Reeves is in "Little Buddha", when Keanu Reeves plays the role of Lord Buddha and alone beats all the entire evil army of Mara, the Buddhist Lord of Evil.
This is the second and final time Kenny is killed in this season. The first was in the episode that aired right before this, Wing.
While the catchphrase "Oh, my God! They killed Kenny! You bastards!" is not uttered in its entirety during the episode, although it is referenced twice: Once during the protests, Kyle leads the protesters by yelling, "Don't kill Kenny!" with the crowd responding, "You Bastards!" After removing the feeding tube which leads to Kenny's final death (so far) and return to heaven, Archangel Michael happily observes, "Oh my God! They killed Kenny!"
Heaven recruiting its ultimate hero through a video game is a reference to the film The Last Starfighter, wherein a young man is chosen to defend an alien race based on his skills at an arcade game that the aliens placed on earth to test humans.
Kenny's death is a reference to the death of Terri Schiavo, who died under similar circumstances.
This is Satan's first appearance after 5 seasons. As his last appearance was in "Probably", although he was mentioned in "A Ladder to Heaven".
At the beginning of the episode, the line for the PSPs extends far down the street - Annie Faulk can be seen in the middle of the queue. After being told to go to the back, Cartman gets in queue, where Annie is now at the back rather than in the middle.
Also in the queue, the same parent - a brown haired woman in a black jacket and jeans - can be seen twice at one point.
Colorado is misspelled as "Colorodo" on the Courthouse at the beginning of the scene in which Cartman goes to court.
Kenny dies several times through this episode. First after being struck down by a car, he is killed. However, the doctors then save his body, although he is brain-dead. The feeding tube that keeps Kenny alive is then removed, killing him again.
