According to my martial arts aficionado husband, there's also a whole move where guys just jump onto a person and literally go for the jugular. OMG! I also rather like the tires in the background for the extra streety effect.
Actually, the discussion of avoiding the pesky hydroplaning effect when attempting to tear at a guy's flesh could actually be useful to anyone writing books featuring zombies or miscellaneous non-pointy-tooth biting paranormals.
