Linger Awhile by Russell Hoban

A lonely, aging widower becomes obsessed with a long-dead B-movie actress and, using a dubious scientific process, draws her out of an old film into present-day London as a seductive, blood-dependent revenant. As his infatuation deepens, the real-world consequences of reviving a fantasy escalate, blending dark comedy with reflections on desire, aging, mortality, and the haunting power of cinema.
