They've done the right thing at CBS in casting -- at least it seems right. Brooklyn native Rosie Perez will play Lorna, Geena Davis' cop partner on the force in Exit 19. I say it's the right thing, and good casting, because Lorna is supposed to be a Brooklyn girl. You can't get more authentic than Rosie Perez. She's a New Yorker through and through. In Exit 19, with Geena cast as a cop who works in the city while raising two kids in Long Island, the work atmosphere will likely seem a lot more realistic with Perez as her partner. If they can muster up the chemistry of a Cagney & Lacey, they'll be well on their way to a success. Of course, with Rosie all of five feet, one and a half inches and Geena a statuesque six feet, they're going to look like Mutt and Jeff.
