Well my suggestion isn't for the underlying theme music that tends to resonate throughout the movies like Linkin Park's efforts, but more so for a specific action sequence or scene.

I'd like to see Fear Factory or my personal Favourite Rammstein , they certainly worked well for Lost Highway (Rammstein) and xXx (Feuer Frei!).

I personally don't think you'll find a Band with a more Robotic sound than Fear Factory though.
