SEMcast is a year old! Holy crap, right? And to help us celebrate the occasion, filmmaker Jeremy LaLonde — whosenew comedy How to Plan an Orgy in a Small Town opens the Canadian Film Festival in Toronto March 30th — comes to the basement with a stone classic: Woody Allen’s Annie Hall, the 1977 comedy that captured a culture and defined a genre. Your genial host Norm Wilner has Marshall McLuhan waiting in the wings.
