Brad Pitt's Sexy Smirk

Here is the latest batch of Brad Pitt from Tuesday on the set of The Curious Case of Benjamin Button in Old Montreal, Canada.

Pitt filed exterior shots around the city for the mind-bending romance that is due out in Fall 2008. This is the tail end of a long shoot, which included four months in New Orleans and another two months in Los Angeles.

Brad is expected be in town for only eight days before, presumably, returning to his family in Prague, where Angelina Jolie is filming action thriller Wanted.
