The Internecine Project (1974)

James Coburn is a current (or former, not made clear) CIA agent who possibly played both sides of the fence. His current cover is a Harvard economics professor, and, surprise, he suddenly gets appointed to be the president's economic advisor. Only four associates know his true identity and shady dealings, so he sets out to eliminate them all in one night. Not by doing the job himself, but by having the four (unbeknownst to them) knock each other off in a series of elaborate plans concocted by Coburn. A great fucking idea, all carried off with sinister, 1970s panache. Just when the film starts to lag (There is a love story with Lee Grant that is annoying and totally unnecessary) it starts cooking again. One of those modest, under-the-radar movies that if you came across it on late-night television, would keep you up until the end credits. This is overdue for a re-make.
