By 1964, it was possible for a major studio to make a film touching upon the Spanish Civil War without having to answer to some senate investigating committee or other. Based on Emeric Pressburger's novel A Mouse on Sunday, Behold a Pale Horse stars Gregory Peck as a war veteran who continues waging a one-man offensive years after hostilities have officially ceased. Exiled to France, Peck is lured back to Spain by vengeful police captain Anthony Quinn. Priest Omar Sharif advises Peck that he's being tricked, but Peck is determined to return to Spain to bid farewell to his dying mother Mildred Dunnock. Halfway through, the film bogs down into ponderous preachifying and moralizing, but overall the film is worth a glance. In 1966, Behold a Pale Horse was scheduled to be telecast on a major American network, but was cancelled at the last minute, reportedly at the behest of the Spanish government.
