Did You Know?

A Canadian Social Insurance Number (SIN) card is used as part of a tripwire for the trap on Vinny's farm that explodes approximately 30 minutes into the film. It is the real SIN card for Cordell Wynne, line producer for the movie, which reveals that his middle name is 'Gerald'.See more »

"Come on, come on. Let's go!", 10 April 2011
Author: lost-in-limbo from the Mad Hatter's tea party.

This low-cost Canadian produced presentation is reasonably ordinary, but for its type not as terrible as it's made out to be. This is one of those films that the cover artwork always made it look quite interesting, but the synopsis on the back had less of an affect. A friend of mine convinced me to watch it, after the first half-hour I could see why because the story does such a great job setting up the highly-charged, innovative predicament (three astronauts in space watch on as world war three erupts with nuclear attacks on Earth) to only lose its way when a couple months later they crash-land back on earth then it becomes a very vanilla-like post-apocalyptic Sci-fi wasteland survival outing (of the very cheap, rancid b-grade kind) with some very unbelievably trite villains that come off more as joke than anything truly threatening. The head honcho played by Kevin King seemed more suited in a "Save by the Bell" episode, than as a ruthlessly imposing leader. At times I was waiting for cued laughter from an audience whenever he was on screen, as he came off more so a brat. Just as poor was Tim Choate in the leading role. Well more so eccentrically annoying. I found the support to be much better; Kate Lynch, Lenore Zann (running around in a school uniform), Maury Chaykin and John Walsch. The opening first half-hour is very well pulled off; with some striking visuals, solid set-designs and usefully gripping details. You could see where all the money went in to, but that could probably explain its weakly conceived abrupt ending. Maybe that had run out. Anyhow during its grounded action, it does create some nasty touches, edgy activity and cement an ugly intensity. Too bad it just too daft (simply lacking the colourful craziness) and at times incoherent. The story is straight-forward, although the script is flimsy and too black and white to make it completely fulfilling. Minimally junky and grim, if particularly plain post-nuke entertainment.
