Did You Know?


"Karl Rossum" is undoubtedly a combination of the name of Czech author Karel Capek and "R.U.R. (Rossum's Universal Robots)," the play written by Capek which is credited with coining the word "robot" (Czech for "slave") as it is used now. In this episode, Karl Rossum invents "duplicants"; i.e., robots. See more »

homage to blade runner
26 September 2006 | by (United States) – See all my reviews

William sanderson doing the voice of karl rossum is wonderful, as he the role is essentially the same in blade runner, as sebastian the genetic replicant engineer. Heart of Steel was one of my favorite episodes when I was a kid, and HARDAC is on my mind from time to time! I just watched Blade Runner and noticed their voices were the same so I came to IMDb to check it out. I probably haven't seen this episode in ten years, so I was pretty happy to have picked up on it. I think it tipped me off when Sanderson says he " built his friends". Whomever was doing the voice casting for this particular role definitely has good taste.
