Boston - Tom Cruise and Cameron Diaz continue work on their upcoming film, "Wichita," in Boston, Massachusetts on September 23, 2009. Well, that's what you call "grinding". Just yesterday when Tom Cruise's wife Katie Holmes was spotted dropping by at the set of the said flick with their kid Suri.

Cruise filmed an exciting car chase and shoot out scene with the help of a stunt double, while Diaz spent time chatting up a handsome member of the Boston Fire Department! Oopsy, looks like Cameron loves Boston, I love her smile!
