Once and Again actor Billy Campbell is confirming rumors that his acclaimed ABC series may return in the fall for a fourth season despite the fact that last Monday's episode was billed by the network as the show's series finale. Campbell's leading lady, Sela Ward, broke the news to him last week. "She called and said, 'Have you heard? It's not definite that we're cancelled,'" he tells TV Guide Online. "Apparently, on the same day that they cancelled us, [ABC] called the studio and said, 'Don't knock down the sets, don't release the actors, and why don't you work us up a tentative budget for a Year Four.' I don't know what to think... They can't even kill us with dignity." Responds an ABC rep: "Once and Again has had its series finale on ABC."
