Apparently, cadavers aren't the only bodies that interest Mac Taylor. This fall, Gary Sinise's CSI:NY detective--whose wife died on 9/11--will have a new romance. Clair Forlani ("Meet Joe Black") has been tapped to play Mac's love interest after producers--who wanted to show Mac's personal side in the third season--whittled down a list of actresses. "It was very challenging," executive producer Anthony E. Zuiker says. "We had to choose someone who's beautiful, talented and could hold her ground with Gary." Forlani will play medical examiner Dr. Peyton Driscoll, who'll make her debut in a "very sexually interesting situation," says Zuiker. She'll have a four-episode arc starting on the season premiere, but producers may choose to extend Forlani's ride. Promises Zuiker, "It will be a fasten-your-seatbelt situation."
