I don't believe I've seen Dummy. But I just remembered another film with her where she gets to show off her fighting "skills", Ultraviolet. Now that was a bad film despite all the shining colors. She basically has different outfit and hair color every few scenes. It's the same director that made Equilibrium with all the cool gun kata. Well that's not a particularly good film either, I watched it to drool over Christian Bale
. But, Ultraviolet is on another level of crapiness.
