Trivia

The bulk of the movie was filmed in The Chiselhurst Caves to enhance the production value, but resetting lights and moving cameras around the natural rock formations proved to be problematic and time consuming. See more »

oh dear....
31 May 2005 | by cpuukSee all my reviews

The script is the main culprit, with terrible lines and cliché scenes written for 4 year old to ponder upon: The number of times the cast members are sent out into the corridor (ones & twos) to be done-in by a rabid Ms Gleeson beggars belief! And each time they fall over\ stand still so as to allow themselves to be dispatched in some very poorly choreographed fight scene- did I say fight scene? I meant rolling around on the ground. I can only guess that they ran out of plot devices on day 1.

The Director should also stand up and take a bow, as a lot of the fault lies there. The subject matter may have been "maverick" but it was executed in a terrible way- B movie slasher style. He should have realised that this plot line was about as believable as politician election promise.

My sympathy goes to the cast, who were made to say the lines and roll around on the ground. They put in bad performances all round, with only Ms Gleeson showing an occasional dabble of acting skill.

If MST3K ever wanted to do a schlock SF horror, this would be the one to go for.
