At last night’s “Darker Side of Green†debate, a launch for Lexus’s new hybrid car, Gretchen Mol warned that even though she plays a twenties-era Atlantic City dancer in the upcoming HBO series Boardwalk Empire (currently filming, and slated to air next fall), we should not expect Showgirls II. “Showgirls then didn’t dance,†she explained, “because it was all about looking nude without being totally naked. So you didn’t move, because that was considered to be too titillating and too pornographic, because then stuff would shake and move. This was supposed to be art. So it’s like, posing, and then you shift and pose again.†Fair enough!
