Here he is below, shooting a scene from A History of Violence in 2004. (This link takes you to a review of the film from DarkEyeSocket in October 2008 - word of warning: it's in need of some revision and a judicious edit.)
He's currently in post-production on his 19th feature film (I'm including mini-features Stereo and Crimes of the Future) A Dangerous Method, due out later this year or early 2012. I hope he's spending his birthday in true Cronenberg style - plugging into an eXistenZ game pod, say, or surfing late night channels for the next airing of Videodrome.

Long Live the New Flesh! Long Live David Cronenberg!
