This entry is part of my "Videodroming Project," which you can read about here. Basically, it is to record my impressions of entertainment media that I watch...with a view especially to semiotics -- or how entertainment programming and commercials draw on the social and political issues of the day. So Wednesday night I flipped on "Life on Mars," not knowing anything about it. I was pleasantly surprised to find that it had a first-rate supporting cast: Michael Imperioli (of "The Sopranos"), Gretchen Mol and the one-and-only Harvey Keitel. Basically, it is about a man who is from the present day, but has been magically transported back to 1973, where he works as a detective in an NYC precinct under Keitel, with Imperioli and Mol as his cops-in-arms.
