Proof of Life is a 2000 American action thriller film directed and produced by Taylor Hackford, and starring Meg Ryan and Russell Crowe. The title refers to a phrase commonly used to indicate proof that a kidnap victim is still alive. The film's screenplay was written by Tony Gilroy, who also was an executive producer, and was inspired by William Prochnau's Vanity Fair magazine article "Adventures in the Ransom Trade", and Thomas Hargrove's book Long March to Freedom, in which Hargrove recounts how his release was negotiated by Thomas Clayton, who went on to be the founder of kidnap-for-ransom consultancy Clayton Consultants, Inc.

Proof of Life was released on December 8, 2000, by Warner Bros. Pictures. It received mixed reviews and underperformed at the box office, as it only grossed $62 million against a production budget of $65 million.

Alice Bowman moves to the (fictional) South American country of Tecala because her engineer husband, Peter Bowman, has been hired to help build a new dam for oil company Quad Carbon. While driving one morning through the city, Peter is caught in traffic and then ambushed and abducted by guerrilla rebels of the Liberation Army of Tecala (ELT). Believing that Peter is working on Quad Carbon's oil pipeline, ELT soldiers lead him through the jungle.

Terry Thorne, a former member of the British Special Air Service, arrives in Tecala fresh from a successful hostage rescue in Chechnya. As an expert negotiator in kidnapping-and-ransom cases, he is assigned by his company, Luthan Risk, to bargain for Peter's safe return. Unfortunately, it is learned that Quad Carbon is on the verge of bankruptcy and takeover, and therefore has no insurance coverage for kidnapping, so they cannot afford Thorne's services. Despite Alice's pleas to stay, Thorne leaves the country. Alice is then assigned a corrupt local hostage negotiator, who immediately urges her to pay the ELT's first ransom demand: a $50,000 "good faith" payment. Not knowing what to do, Alice agrees, but the transaction is stopped by Thorne who (due to his conscience) has returned to help. He is aided by Dino, a competing negotiator and ex–Green Beret.

Over the next few months, Thorne uses a radio to speak with an ELT contact, and the two argue over terms for Peter's release—including a ransom payment that Alice can afford. Thorne and Alice bond through the ordeal, and become intimate. They eventually negotiate a sum of $650,000.

Meanwhile, Peter has become a prisoner at the ELT's jungle base camp. There, he befriends another hostage named Kessler—a missionary and former member of the French Foreign Legion—who has lived in the camp for nineteen months. The two plan and attempt to escape but are soon tracked by the ELT. As they travel through the jungle, Peter steps on a trap and is unable to continue. Encouraged by Peter to flee, Kessler leaves him behind and later hears a shot fired. Kessler is shot in the shoulder by rebels and falls off a cliff and into a river. Kessler is found and hospitalized. Thorne's ELT contact subsequently refuses to respond to his calls. Luckily, one of Alice's young maids recognizes his voice over the radio and reveals he is a government official. Thorne confronts the contact, who confirms that Peter is alive, but because of the ELT's escalating war with the government and Peter's knowledge of the terrain, the ELT will no longer negotiate.

At Thorne's urging, Alice and Kessler convince the Tecala government that the ELT is mounting an attack on the pipeline being built through their territory. This forces the government army to mobilize, thus forcing a bulk of the camp's ELT troops to mobilize for a counter-attack. Thorne, Dino, and several associates are then inserted by helicopter and raid the weakened ELT base. They overcome the camp's soldiers, free Peter and another hostage, and then fly back to the city, where Alice happily reunites with her husband. Thorne and Alice share a final intimate moment before the latter departs with Peter on an immediate flight to the U.S..

Although the producers wanted to film in Colombia, due to the dangers that guerrillas posed in that country at the time, the movie was mainly filmed in Ecuador. Tecala's geographic and urban appearance and its political characteristics were based loosely on a mix of several Andean countries.
