Trek fan or not you should check this out. Three guys from the US, England, and the Netherlands made this thing. It features characters from every incarnation of Star Trek. The battle scenes are the best looking thins in it and you'll love the way they resurrected the characters.

That's really cool, and impressive for something put together by some fans. I wish it were a real movie - it would be the first decent Trek movie in years.
