Project X (1987 film)

Project X is a 1987 American comedy-drama directed by Jonathan Kaplan, in which Air Force pilot Jimmy Garrett (Matthew Broderick), assigned to a secret military laboratory, discovers that the chimpanzees he supervises are being trained on flight simulators and then exposed to lethal doses of radiation to study how pilot performance would degrade after a nuclear attack. Helen Hunt co-stars as Teri, the university researcher who taught the chimpanzee Virgil American Sign Language. The film was produced by Walter F. Parkes and Lawrence Lasker, written by Lasker and Stanley Weiser, and released by Twentieth Century Fox on April 17, 1987.¹^•²

Plot

Virgil, a young chimpanzee raised by the psychologist Teri Macdonald (Helen Hunt) and taught to communicate in American Sign Language, is sent to the fictional Lockridge Air Force Base when university funds for his upkeep run out.⁷^•¹ There he joins a group of chimpanzees trained to operate flight simulators as part of the secret Project X. Jimmy Garrett, a would-be fighter pilot grounded after a disciplinary offense, is assigned to the laboratory and discovers he can interact with Virgil through signing; the two form a close bond.²^•⁷

Jimmy then learns the experiment's purpose: after simulator training, the chimpanzees are exposed to lethal radiation to determine how long human pilots could perform after a nuclear exchange. Roger Ebert, the longtime film critic of the Chicago Sun-Times, noted that the film itself acknowledges the experiment's logical flaw through Broderick's character: human pilots would know they had been irradiated, and that knowledge would affect their performance, while the chimps' behavior would not.² Once Jimmy realizes the chimps will die, he enlists Teri's help to rescue Virgil. Virgil has meanwhile warned the other chimps; their first escape attempt is foiled, but they eventually hijack a military plane and gain their freedom by crash landing in the Everglades and evading capture.⁷

The film opens with the statement: "To predict the performance of pilots during wartime conditions, the military has developed programs to test the limits of human endurance. The following is inspired by actual experiments by the United States Air Force."¹

Real-world basis

The experiments depicted were not invented for the film. The philosopher Peter Singer, author of Animal Liberation (1975), described the real program in his work: experiments conducted over many years at Brooks Air Force Base in Texas, with variations continuing at the time he wrote, used a device called the Primate Equilibrium Platform (PEP), a platform that pitches and rolls like an airplane while the animal sits in a chair and manipulates controls in front of it.⁵ Singer argued that the film gave many Americans their first glimpse of animal experiments carried out by the armed forces, but presented a softened version of what actually happened to the animals.⁵

The screenwriters could not gain access to facilities where animal research occurred, but recruited people who had been involved in such experiments to help with details.¹

Production

The project began when producer Lawrence Lasker discussed a film about research animals with screenwriter Stanley Weiser; eighteen months later Weiser saw a newspaper article about military research on animals and the story took shape, with Lasker's partner Walter F. Parkes joining them.¹ The story was first developed at Warner Bros. for director John Badham, but Warner Bros. wanted small men in monkey suits rather than chimpanzees. When Lasker insisted on real chimps, Warner passed, and Barry Diller, head of 20th Century Fox, took over the project.¹

Producers sought young, untrained chimpanzees, since older chimps tend to be more aggressive and have learned bad habits; the young chimps were purchased from zoos and medical research laboratories, and some were rented from trainers. Willie, the three-year-old who played Virgil, was found at a medical research facility where he had interacted only with staff. Although sign-language programs for chimps exist, Willie was not taught the language; over four months he was taught to sign on cue without associating meaning with the signs.¹

Animal trainer Ron Oxley worked with the chimps through six months of pre-production, including a month of flight-simulator training, but died days before principal photography began; Hubert Wells took over. Each chimp had an individual trainer on set, and the set was built with large pillars for trainers to hide behind and give instructions during filming.¹

Principal photography began on January 20, 1986, on three soundstages on the Fox lot in Los Angeles, with exteriors at Camarillo Airport, the Tillman Reclamation Plant, and Van Nuys Airport. The film wrapped on May 16, 1986.¹ Originally scheduled for release on December 12, 1986, the opening was pushed back to spring 1987.¹

Release and box office

Sneak previews ran on 350 screens nationwide the weekend before release to build word of mouth. Marketing research showed that most people associated chimpanzees with comedies and monkey hijinks, so the print advertising campaign focused on Matthew Broderick and avoided showing the chimps.¹

The film opened on 1,022 screens on April 17, 1987, earning $3,309,985 in its first three days, about 17.9 percent of its eventual domestic total. It peaked at 1,025 theaters and ran an average of 4.9 weeks per theater, finishing with $18,532,286 domestically and $21,589,395 worldwide.¹^•³^•⁴

Animal abuse controversy

Shortly after the opening, the film faced charges of animal abuse during filming. Bob Barker, host of the television game show The Price Is Right and an animal rights activist, placed an advertisement in the May 8, 1987 Daily Variety offering a $5,000 reward for witnesses to abuse. He said he had been informed that trainers beat chimpanzees with rubber clubs known as "blackjacks" to establish dominance; producers Lasker and Parkes denied the charges.¹

In June 1987, Barker and the Society Against Vivisection held a press conference at which film technician Paul Mueller, who is not listed in the onscreen credits, said he witnessed chimps being beaten during filming of a flight simulation sequence. Barker said at least six other people told him they had witnessed abuse but feared losing future work if identified as whistleblowers. Trainer Hubert Wells refuted the charges, saying the animals were occasionally spanked but never beaten with a blackjack, and the American Humane Association, whose representatives were on set for all eighty-one days of filming, said it witnessed no abuse or mistreatment.¹

In November 1987, the Los Angeles City Department of Animal Regulation asked the district attorney to open an investigation. The district attorney declined to file misdemeanor charges because the one-year statute of limitations had run out, and felony charges were not applicable; a look into civil charges was dropped in April 1988 for lack of sufficient evidence.¹ A report filed in October 1987 by the Los Angeles Department of Animal Regulation stated that at least six trainers employed by Twentieth Century Fox had physically or mentally abused chimpanzees during production.⁸

When filming wrapped, the chimpanzees purchased for the movie were donated to Primarily Primates, an animal refuge in Texas, and 20th Century Fox donated $35,000 to the center for their care.¹

Reception and themes

Ebert gave the film a positive review, writing that Virgil, the gifted chimpanzee, deserved co-star billing alongside Broderick and calling that one of the movie's strengths.² Desson Howe, reviewing for The Washington Post, was more critical, describing the film as following the formula of every lovable-creature picture from National Velvet to E.T., a human bonding with an endearing nonhuman against society, and judging that the payoff never quite happens, though he credited Kaplan with controlling the animal-human interaction admirably.⁹ A letter in the Los Angeles Times observed that it was hard to recall another commercial film dealing extensively with vivisection that achieved theatrical release, and argued the film's value lay in raising questions about the value of non-human life without telling viewers what to conclude.¹⁰

Commentators have read the film as science fiction that subverts the genre's usual concerns: instead of artificial intelligence unsettling human dominance, it uses chimpanzees, the species closest to humans, to challenge animal exploitation, and its ending, in which the chimps escape using the very flight skills the military taught them, reverses the assumed hierarchy between humans and animals.⁷ Howe noted the continuity with Parkes and Lasker's earlier WarGames, which likewise cast a skeptical eye on military technology.⁹
