    Rugged adventurer John Hamilton (a solid and likable performance by Michael Dudikoff) gets hired by a team of shady folks with assorted secret agendas to find a fabled lost city located in the Amazon. Things go awry when the search party stumbles across evil Nazi scientist Dr. Wolfgang Manteuffel (a nicely sinister portrayal by Robert Vaughn).

    Adequately directed in workmanlike fashion by the usually more competent and on the money Steve Carver (whose other much better films include "Big Bad Mama," "The Arena," "An Eye for an Eye," and "Lone Wolf McQuade"), with an often sluggish pace, an overly convoluted script by Andrew Deutsch and Edward Sampson that gets bogged down in rather tedious talk, and infrequent, but still decently staged action scenes, this one has all the essential ingredients -- Nazis, a band of scurvy pirates, a tribe of deadly cannibals, plenty of treacherous back-stabbing characters, and a few okay plot twists -- to qualify as a possible contender, but alas the fairly tepid execution fails to make all these promising elements cohere into an exciting and satisfying whole. Fortunately, a fine supporting cast of reliable veteran thespians ensures that this picture remains watchable: Donald Pleasence as the shifty Heinrich Spaatz, Herbert Lom as the corrupt Colonel Ricardo Diaz, and L.Q. Jones as grizzled old rascal Eddie Hiller. Moreover, there's yummy distaff eye candy in the fetching forms of Sarah Maur Thorp as the sweet Anna Blakesley, Cynthia Erland as Spaatz's sexy secretary Maria, and Foziah Davidson as the tough Dalia. Both Avraham Karpick's slick cinematography and Sasha Matson's moody score are up to par. An acceptable diversion.
