This sequence was my homage/spoof of Pink Floyd's "The Wall". Animating the hammers marching is done in a couple minutes these, days with digital technology: animate one hammer with a pivot point and copy and paste the others... super easy. But back in 1982 the hammer sequence was a lot of work, and an amazing piece of animation. And oh yeah, that's our recurring character in the bottom pic. He's a Hitler Highway Patrol Cop. It just made sense to have him marching behind the hammers... almost kinda profound.
