Old-fashioned story with a little bit of love story, a little bit of action and a lot of nothing much. Gerald Browne's novel of the same name is the basis of this adventure film, the first of two made by Ernest Day, he was the cinematographer of classics such as Clockwork Orange and Lawrence of Arabia. For his debut, it took years to be released in the United States due to the difficulty of finding a distributor to exhibite this film despite containing a great trio of famous actors at the time. It deals with an expert electronics engineer named Wiley (Ryan O'Neal) leaves New York for Mexico City, where he will meet the beautiful Holbrook (Anne Archer). Together, they will live a whole series of adventures while getting involved with a brutal South American government. In Mexico, both will meet the strange and mysterious Argenti (Omar Shariff) and discover that, right in the hotel where they are staying, there is a magnificent and spectacular collection of emeralds. From here, they will find themselves involved in the dangerous world of Latin smuggling of precious stones...He wanted adventure...She craved revenge...Emeralds held the answer. Driven by lust, greed and revenge . . .to the edge of disaster. The prize. . . A fortune in emeralds!. Hot excitement and gem of a thriller !.

Attractive and decent adventure/intrigue movie with good guy Ryan O'Neal, bad guy Omar Shariff and Anne Archer as the woman in between. A mediocre attempt to make a jolly romantic comedy set against background of torture, murder and rebel guerrillas being fed to the hogs of prisons of Colombia. This agreeable thriller/comedy-adventure blends noisy action, rip roaring, a love story, cliff hunger, and being fun and entertaining enough. Ryan O'Neal gives a sympathetic acting as an American electronics expert get in trouble and plans a heist with his girlfriend and other cohorts. His colleague is the gorgeous Archer; both of whom play a couple of Americans meeting cute in Mexico, then heading for Colombia where she takes over from her missing sister who's working for the rebel cause and he - at first with itchy fingers for the loot- helps her replenish the rebel coffer through a daring heist of emeralds from a strong-hold right out of a James Bond movie with Omar Shariff as a villain to match. Trio de protagonists are well accompanied by nice secondaries, such as: the later very famous John Larroquette, Philip Stone, Michael Sheard and ordinary Mexican actors, such as: Enrique Lucero, Manuel Ojeda and Miguel Ángel Fuentes.

The picture contains spectacular and lively scenarios, some nice stunts and funny lines. It is also worth highlighting the film's catching soundtrack, which marked the first foray into film music by the Rolling Stones' first bassist, Bill Wyman. Colorful and sunny cinematography by Gilbert Taylor, although an urgent and perfect remastering is extremely necessary. Being shot on various locations from Manzanillo, Colima, México, Nueva York, and Studio, some interior scenes: Shepperton Studios, Shepperton, Surrey, England, and Elstree Studios, Borehamwood, Hertfordshire, United Kingdom. The motion picture was mediocre but professionally directed by Ernerst Day. He was a notorious cameraman in several films as The Secret Partner, A passage to India, Sphinx , Running scared, The Long Day's Dying and a director assistant as The spy who love me, Operation: Daybreak, Moonraker, The Adventurers. The film will have you on the edge of your seat but the adventure and action never let up. It's a winner for Ryan O´Neal, Anne Archer and Omar Shariff fans. Rating: 5.5/10. Average but passable and acceptable.
