Gillette is running some interesting ads about how Superman shaves and they are asking many famous faces to come up with their best answer. The ads are part of a promotion for the upcoming film Superman: Man of Steel. I’m actually enjoying a lot of the responses in each video, even though I know it’s most likely going to be all about a Gillette razor. The videos are no less interesting though, especially when we get to hear Bill Nye offer up his best theory.
