The Hills Have Eyes 2 is a 2007 American horror film and the sequel to the 2006 film, which itself was a remake of the 1977 horror film. The film follows several U.S. Army National Guard comrades as they fight for survival against the mutant people living in a military base in the New Mexico desert. It stars Michael McMillian, Jacob Vargas, Flex Alexander and Jessica Stroup. The Hills Have Eyes 2 was directed by German film director Martin Weisz and written by father and son team Wes and Jonathan Craven.^[3] A graphic novel titled The Hills Have Eyes: The Beginning was published by Fox Atomic Comics to accompany the release of the film; it was released July 3, 2007.

A captive woman, forced to breed mutant children, is unable to provide healthy offspring after giving birth to a stillborn and is killed by Papa Hades, leader of the inbred mutant clan living at a nuclear testing village in the New Mexico desert, designated as Sector 16. Following the events of the first film, the United States Department of Defense sent a military army to occupy the location and exterminate the remainder of the mutant clan. Colonel Lincoln Redding and a trio of scientists who are working in that area on installing a surveillance system are attacked by the mutants.

Later, a group of National Guardsmen in training led by Sergeant Jeffrey "Sarge" Millstone are sent into the desert to resupply the scientists. They arrive to find the base camp abandoned after the mutants' attack. When the soldiers pick up a faint distress call, Sarge organizes a search and rescue mission through the hills. Napoleon and Amber, who stay behind at the camp, find and retrieve one of the missing scientists out of the camp's portable toilet, but he dies before he can warn them. The two are then attacked by the mutants, who destroy their transport and steal their weapons, forcing them to run into the hills to warn the others. The search party is attacked by the mutants; Mickey is pulled into a bolt-hole and killed by Stabber, and Sarge is accidentally shot dead by Spitter's friendly fire just before Napoleon and Amber reunite with the group. Spitter is killed after one of the mutants sabotages his rappelling gear as the others try to lower him down the hill. With their remaining gear stolen, they are forced to try to find another way to escape.

The remaining troops soon locate Redding, mortally wounded and unhinged from the mutant's attack. He warns them of the mutants' plans to capture women for breeding and reveals an exit route through the mining caves before committing suicide. After the group kills Stabber, Missy is captured and taken into the mining caves by Chameleon, forcing the other troops to rescue her. Stump leaves the group to escape on his own before being pursued and killed by Letch while attempting to climb down the hill. Separating from Crank and Delmar, Napoleon and Amber cross paths with Chameleon, whom they manage to kill. While escaping Sniffer, they are rescued by a nonviolent mutant named Hansel; Sniffer encounters Crank and Delmar, shoots the latter with one of the group's M4 carbines and is killed by Crank in retaliation. While Hansel leads them to the exit, Delmar dies from his wounds after arriving at the mine’s doorway. Napoleon joins Amber to save Missy. Crank, who is attempting to unlock the blast door, dies when accidentally triggering an explosion of a crate of dynamite that he attempts to take with him.

After killing Letch, Napoleon and Amber locate Missy who is being savagely raped by Papa Hades. After distracting him, they manage to free her, but Hades soon returns and attacks them, triggering a vicious fight until the trio finally subdues and kills the mutant leader with a bayonet. As the survivors prepare to depart the mines, they are watched by an unknown mutant using their surveillance equipment.

Writer Wes Craven's initial inspiration for the film came during a casual conversation with producer Peter Locke. Craven envisioned that the previous film's character, Brenda (Emilie de Ravin), traumatized by her suffering during the events of The Hills Have Eyes, joins the National Guard to overcome her fears. Barely finished with basic training, Brenda receives a call from her sergeant, who explains that they are sending a team back to the New Mexico desert to eradicate the remaining mutants. Her sergeant and the team need her, for she is the only one left alive who knows the mutants' location. Because of de Ravin's involvement in the television show Lost, her schedule was unable to accommodate the filming of the sequel. Wes Craven replaced her character, but retained much of the original concept, including the group of National Guard soldiers in training.^[4]

Craven originally looked at M. J. Bassett, the director of Deathwatch, to take over the directing role, but ultimately chose Martin Weisz after scheduling conflicts with Bassett. The Hills Have Eyes 2 had a budget of $15 million,^[5] and began filming in the summer of 2006 in Ouarzazate, Morocco, where the previous movie was filmed.

The Hills Have Eyes 2 was released in theatres on March 23, 2007.^[6] The film was released on DVD on July 17, 2007, by 20th Century Fox Home Entertainment.^[7] The Hills Have Eyes 2 also grossed over $30 million in domestic DVD sales, for a total of $67,915,885.^[8]

The total gross at the box office of The Hills Have Eyes 2 was $37.6 million, about half of the original's total gross.^[11]

The soundtrack was released on July 31, 2007 via Bulletproof Records.^[17]
