NECA wins points for having the first action figure with a head in mid-explosion. Holy crap, I hope this gets into production.
The following figures are all from Gears of War - the mockups are larger than life, the small black versions will be production size.
A great scene from the Exorcist
David Bowie in Legend
Aliens VS Predator
Shaw Brothers action figures
They had some sweet looking Teenage Mutant Ninja Turtles figures - these appear inspired by the original Eastman and Laird comics.
