I purchased the novelization of this movie long before I saw it - in fact, I missed it at the theater for whatever reason and only caught up with it on home video. I really don't know why that was, because I'd read the book and thought the story - boy plays video game, little knowing it's really an audition for a real space war - was wonderful.
I thoroughly enjoyed the movie too - Lance Guest and Catherine Mary Stewart are the youngins; Dan O'Herlihy and Robert Preston are the old pros, and it's a terrific little flick. There are some really cool behind the scenes factoids too: director Nick Castle played Michael Myers (The Shape) in
Halloween (1978); and this movie is the first to do all of its space visual effects with computer animation! (Yes, they're slightly primitive - but better than you'd expect from thirty years ago!)
Yes, this is the preview, or teaser, poster - but I actually like it better than the release poster - plus, this was what the cover to the novelization looked like - and it was truly eyecatching.
Until next post-er, you Can Poke Me With A Fork, Cause I Am Outta Here!
