It's "libber" (Holly Hunter) vs. "lobber" (Ron Silver) in a chronicle of tennis's Battle of the Sexes---the 1973 Billie Jean King-Bobby Riggs encounter, a good-natured event that's tailor-made for the wry comic sensibility of writer-director Jane Anderson (who wrote "The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom"). Here, Riggs isn't a villain, just an aging tennis hustler out for one last fling. Howard Cosell: Fred Willard.
