Jim McCann is into daytime dramas. Really. The 1996 graduate and aspiring Nashville screenwriter made his official entry into the daytime television market in April with the airing of his first script for ABC’s “One Life to Live.” The pivotal moment in McCann’s personal drama came in August 2001 when actress/singer Kathy DePaiva, who plays Blair Cramer on the ABC soap, performed at the Grand Ole Opry. McCann approached the actress, who directed him to the network’s writer-development program. Buoyed by this new success, he is currently hard at work on a screenplay and a theater piece.
