The Adventurers is a classic monument to bad taste. Film is marked by profligate and squandered production opulence; inferior, imitative and curiously old-hat direction; banal, ludicrous dialog; sub-standard, lifeless and embarrassing acting; cornball music; indulgent, gratuitous and boring violence; and luridly non-erotic sex.
Harold Robbins guess-who novel about the jet set and South American politics was as commercial as it was trashy; film version may be fairly said to make the novel look better.
Story depicts the life of a South American playboy who, if one were to swallow the specious sociology, was a victim of childhood traumas which crystalized revolutionary violence and brutal rape.
On the romantic front there is Candice Bergen, about the only principal to salvage anything from the film, playing a fabulously wealthy girl who marries the hero, but loses their baby in a swing accident, becomes barren, and eventually turns lesbian.
