If Celine Dion singing My Heart Will Go On over the weekend didn't dredge up some Titanic-sized memories of that blockbuster for you, then maybe the actor who played Jack showing up in town this weekend might. That's correct! It seems Leonardo DiCaprio will be coming to the city on Sunday for a premiere screening of the environmental documentary The 11th Hour, which the actor narrated. There's no word yet on where the private screening will be.

In addition, the Hollywood star of The Departed and Gangs of New York will also drop in on an afternoon event for HSBC's new 'green' credit card. In case you weren't aware, DiCaprio is a big activist for global warming and other environmental causes, so that's why he's plugging a card that is apparently made without chlorine or toxic materials and will support various green causes (although, you have to wonder what kind of carbon footprint it might leave behind when you start putting some damage on it). However, what we really wonder is if DiCaprio will be chauffeured into town in a big gas-belching limo or will he actually do the green thing and ride the Airport Express?
