Congo is a 1995 action adventure film loosely based on Michael Crichton's novel of the same name. It was directed by Frank Marshall (a frequent collaborator of Steven Spielberg, who directed another film based on Crichton's work, Jurassic Park) and stars Laura Linney, Dylan Walsh, Ernie Hudson, Tim Curry, Grant Heslov, and Joe Don Baker. Charles Travis (Bruce Campbell) and Karen Ross (Laura Linney) are testing a communications laser in a remote part of the Congo near a dormant volcano when Charles' friend Jeffrey (Taylor Nichols) discovers an ancient lost city's ruins. When Jeffrey and Charles go to explore it, they are both mysteriously killed. While Karen waits at headquarters, she activates a video feed and sees a destroyed camp with several dead bodies. The camera is then suddenly knocked over by a strange creature, ending the transmission. TraviCom's CEO and Charles' father R.B. Travis (Joe Don Baker) reveals they were really exploring the Congo to find a rare blue diamond that's only found at the volcanic site.
