Planet Terror is the more action-oriented half of Grindhouse. A 2007 Robert Rodriguez film in which a military transaction goes awry and an experimental poison gas is released on a small town in rural Texas, turning the unsuspecting civilians turn into bloodthirsty zombies. The only people who can stop them are a Go-Go-Dancer with a gun for a leg, her expert gunman ex-boyfriend, a pair of crazy babysitter twins, a shellshocked doctor, a Jerkass cop, a crusty sheriff, a scientist obsessed with balls, and many other trailer-park freaks from deep in the Heart of Texas.
"Humanity's last trope...rests on a high-power machine gun":
Muldoon says he delivered one to Osama bin Laden, along with a shot to the chest. Back in 2007, it was kinda funny; in 2011, it became really funny because that's how bin Laden really died.
Brain Food: The zombie-like mutants eat Fergie's brain, prompting the gag "Looks like we've got a no-brainer." Similarly, a repeated line throughout the film is "I'm gonna eat your brain and gain your knowledge," first said as a small boy is playing with his action figures, although by the time Josh Brolin starts saying it, it gets creepy/hilarious.
Bury Your Gays: Tammi is Dakota's lesbian lover on the sly, and ends up getting eaten by zombies.
Exact Words: J.T. mentions that never will his brother share his BBQ recipe, even if he is dying in his brother's arms. When they are both mortally wounded, J.T. shares his recipe and his brother dies in his arms.
Godzilla Threshold: In the wake of the sicko outbreak, the police force breaks out the "All or Nothing" box, which involves giving everyone a badge, a gun, and a deputy rank. Though they still won't let El Wray use a gun.
Groin Attack: Abby seems fond of them, cutting off people's balls and keeping them in a jar. And the rapist soldier's testicles actually melt off.
Her Boyfriend's Jacket: Cherry wears El Wray's leather jacket, much to his chargrin since she left him and he was searching for it for months.
Homage: The action may be all Robert Rodriguez, but the horror suspense elements, down to the synthesizer music, is pure John Carpenter.
Infant Immortality - Averted, in one of the film's only genuinely horrific scenes. Robert Rodriguez said he used his own kid, Rebel, as Tony because he didn't want to 'kill' anyone else's kid.' He also made a less-violent cut of the film where Tony survives the movie for Rebel to watch.
"I'm gonna eat your brain and gain your knowledge."
"It's go-go, not cry-cry"
"No dead bodies for Da-Da tonight."
"What did I tell you, Tony? Don't point the gun at yourself. Didn't I tell you that?"
Leg Cannon: Cherry Darling had her leg eaten by zombies, and replaced it with an M-4 assault rifle, which she used to kick much ass. And then later, she had that replaced with a full-on minigun. It's a bit ambiguous how she fires it, though, since we never see her reaching down to pull a trigger.
Lost In Transmission - The audience sees "MISSING REEL." During the missing reel, it's implied, we'd have gotten to see Rose McGowan totally naked, plus the entire plot surrounding Wray's mysterious origins would have been explained. And when the film comes back, everything's on fire, and we'll never know why. Possibly the best cut in movie history.
There's a Meta-Gag in there as well. A presumed urban legend (re-told in the novel Fight Club) is that older movies would have their nude scenes cut shorter and shorter as projectionists removed a few choice frames for their collection. Notably, all of the sexier bits seem a lot more grainy, as if they've been watched more than the rest of the film.
My God, What Have I Done?: Subverted with Dakota after she gives her son a loaded gun to defend himself with, only to have him shoot himself in the head. She then starts cradling the kill and when her husband shows up, she shrieks blame at him for it.
No Name Given: We don't really know what Cherry's real name is. "Palomita" was just something Wray gave her.
Noodle Incident - The "missing reel". Cut to the diner on fire. Sheriff Hague had been shot. Dakota and her father, the babysitters, the go-go dancing club owner and some of the dancers somehow made it there.
Secret Ingredient: Throughout the first half of the mfilm, JT tries to find the perfect BBQ sauce recipe. Before he tastes a sample, it gets mixed with some of his blood, leading him to correctly deduce from it that all that was missing was a little bit of salt (since human blood tastes salty).
There Is No Kill Like Over Kill: The Rapist (played by Tarantino) tries to have his way with Cherry. He is smashed over the head with a table leg, impaled in the eye by the leg's broken end, has his privates melt off from the infection taking over him, has a syringe launched into his other eye, melts into an inhuman monster, pukes up his guts, then finally is shot in the crotch with a grenade launcher. Good grief.
