Trial Run (1969)

Like Shadow Over Elveron, Trial Run was a made-for-TV film featuring an excellent cast, clever writing, and... Leslie Nielsen. Hal Erickson of Rovi says of it: "Trial Run is a slick, cynical tale of blind ambition. James Franciscus plays a young attorney who'll do anything to reach the top. To this end, Franciscus uses not only his employer Leslie Nielsen, but his faithful secretary Diane Baker, who has long sacrificed her own happiness for Franciscus' advancement. Our 'hero' finally comes acropper as a result of his torrid affair with Nielsen's wife Janice Rule. The ending of this one is a beaut, which is why we're not divulging any more details."
