Kevin Kline is in the zone. The Academy Award-winning actor is so focused on his role as hard-boiled gumshoe Guy Noir that he doesn't notice he's cut his finger as he shoots a scene for the "A Prairie Home Companion" movie in the lobby of the Fitzgerald Theater. Decked out in a pinstriped suit and with his hair slicked back, Kline does take after take, adding funny asides under director Robert Altman's quiet gaze. A.P. reports.
