Clint Eastwood plays James Bond in some unlikely mid-1970s casting. Eastwood directed himself as an art teacher (!) who is actually a government operative (!!). But when an American agent is assassinated in Europe, he's called out of retirement to put the hurt on the men who did it. Based on a novel by Trevanian, the film winds up with Eastwood climbing a mountain in Switzerland and playing a game of kill-or-be-killed with one of his targets. Some decent action, but also a lot of filler. Still, the cast includes George Kennedy and the late Jack Cassidy, whose sharklike smile was perfect for playing a professional killer. --Marshall Fine
