The Prize (1992)

A group of Nobel laureates descend on Stockholm to accept their awards. Among them is American novelist Andrew Craig (Paul Newman), a former literary luminary now writing pulp detective stories to earn a living. Craig, who is infamous for his drinking and womanizing, formulates a wild theory that physics prize winner Dr. Max Stratman (Edward G. Robinson) has been replaced by an impostor, embroiling Craig and his chaperone (Elke Sommer) in a Cold War kidnapping plot.
