This British film set in the US is a fine example of what UK cinema used to be before they adopted gangsters & football hooligans as their only subject matter.

Starring Robert "The Detectives" Powell it revolves around a specialist sent into assist the military in setting up a transmitter deep within an unexplored cave complex. Once inside they discover a lost civilisation who aren't all too happy to see intruders.

Robert Powell is excellent and demonstrates again why he has always been a very underutilized actor. The presentation is brilliant as is the score.

Allegedly the movie was filmed a couple of miles down in a real cave complex, if so that is highly impressive though a fair few scenes look like they were more likely located in a studio.

Not sure why this deserved an R rated but regardless is a damn fine effort and an enjoyable piece of British cinema.

The Good:

Looks great

Robert Powell

Decent story

The Bad:

Falls apart a bit near the end
