Tipster Yoshi infoms us:

On Sunday night, my girlfriend and I spotted a bespectacled Jimmy Fallon at Specs Bar in North Beach, digital camera in hand he looked like any other tourist, except this one knows Horatio Sanz. Anybody there know why he may have been in town?
Well, Yoshi, the buzz up here in Hollywood-North is that Jimmy was in North Beach preparing for his role in an upcoming docu-dramedy-thriller about San Francisco's very own Meredith Brody. It's a family-romantic-horror flick in which he plays a man who will go to any lengths necessary to protect his beloved pet lobster (played by that Wishbone dog) -- which, as we all know, is Meredith's favorite food to review, almost to the point of exclusivity. Though he had to don a fatsuit for his role in the hilarous upcoming hit , rumor has that he'll actually be playing a vegetarian in Don't Bisque Me, Baby. What a freak! Thanks for the tip, Yoshi.Just Friends
