Why does discussing the overlooked 1991 classic “Dead Again” feel like we’re living a past life? Maybe it’s the shock of seeing young Sir Kenneth Branagh (attempting a weird American accent) and Dame Emma Thompson. Maybe it’s Sir Derek Jacobi making us wonder if that stutter is an “I, Claudius” reference. Maybe it’s the whole romantic fantasy thing, with a Hitchcockian past intruding on a 1990s present. - Jason Snell with Glenn Fleishman, Erika Ensign, Annette Wierstra, Dr. Drang and Shannon Sudderth.
