Not just a repeat of 1987’s boiled-bunny tale, this show is about a guy (Joshua Jackson) cheating on his wife (Amanda Peet, 51) with leather-clad Alex (Lizzy Caplan, of Fleishman Is in Trouble), but she’s not depicted as a loathsome villain like Glenn Close’s 1987 Alex. “We’ve got lots of time to really dig more deeply into Alex’s backstory, her childhood, seeing things through her eyes,” Caplan says.
