Tom Cruise is widely noted for his abundance of enthusiasm when it comes to self promotion - think jumping on Oprah Winfrey's couch and five hour marathon autograph sessions at premieres. So it was hardly surprising to see Tom actually holding his own mic as he worked the crowd at MuchMusic in Toronto last night.The former Top Gun star, as usual, put all his might into greeting fans, signing autographs and taking photos while promoting his new movie Valkyrie which opens on Christmas Day. Cruise was also seen leaving CBC's The Hour and leaving his NYC apartment on the same day.
