Based on the novel by Irving Wallace, The Prize takes place in Stockholm, where several laureates gather to accept their Nobel Prizes. At first, the film concentrates on iconoclastic novelist Paul Newman, but he is temporarily shunted to the background when physics expert Edward G. Robinson is kidnaped and replaced by his wicked twin brother. The real Robinson is to be spirited behind the Iron Curtain, while the "fake" Robinson is to disrupt the awards ceremony with an anti-American tirade. Newman gets wind of the plot, and with the help of Swedish foreign office functionary Elke Sommer, he endeavors to rescue the real Robinson and expose the phony-who has yet another trick up his sleeve before the film is over. We'll go along with the fantastic plot convolutions of The Prize, provided we don't have to swallow the premise of another man's voice emanating from that familiar Eddie Robinson mug.
