Well official trailer from the awesome guys at www.Black20.com.
And for those that don't know;
Uwe Boll is a terrible German director who found a loophole in Germany's film funding system where he is guaranteed a load of money even if his films flop. All his work so far consists of awful video game to film adaptations which fit nicely into the category of 'so bad its good'.
Contra (a.k.a Probotector in Europe and Gryzor in Japan) was originally an awesome side scrolling 2D arcade blaster from the 80's which has since spawned several sequels.
