Trivia: When Tammy [Stacey Ferguson of the Black Eyed Peas] tries to hitch a ride at night after her car breaks down, she is attacked by silhouetted zombies. When the first zombie attacks her, hit the pause/slow motion button on your DVD player: you will see a figure in a jacket and he has a bonnet covering his head. That person is Quentin Tarantino.
Trivia: When Tammy's car dies on the side of the road before she gets out of the car the radio says, "In loving memory of jungle Julia." This is a reference to the other half of the grindhouse double feature "Death Proof." Jungle Julia was one of the main characters in the first half of the movie.
Trivia: The man playing Dr. Felix in the movie is Robert Rodriguez's doctor in real life. He was cast because Rodriguez needed someone who could explain all the medical pictures that are being shown on the computer.
Trivia: The man playing Skip is actually not a professional actor. He is Robert Rodriguez's realtor. He was cast for the part because Rodriguez liked his accent.
Trivia: The Latino twin sisters in the film are real-life nieces of writer/director Robert Rodriguez.
Trivia: The little boy playing Doctor Block's son is played by Robert Rodriguez's son, Rebel Rodriguez. Robert actually shot more scenes in which his son survives the entire movie, so that his son didn't know he was killed off.
Trivia: Ever since "Planet Terror," a common misconception among some fans is that lead actor Freddy Rodriguez is related to film maker Robert Rodriguez (probably due to the fact that Robert is known for casting family members in his films). However, Robert and Freddy aren't related at all. Robert Rodriguez was born in San Antonio, Texas, in 1968, of Mexican descent. Freddy was born in Chicago, Illinois, in 1975, of Puerto Rican descent.
Trivia: In the "Planet Terror" segment there is a trailer for a film called "Machete" in which Danny Trejo plays the main character, and is the same name as the character he plays in the "Spy Kids" movies, which is also directed by Robert Rodriguez.
