This was Gary's breakthrough role, in which he played Capt. Jeffrey
McDonald, the army doctor accused of killing his wife and children. A relative
unknown when cast, he plays the leading role in this excellent film and managed to be both sympathetic and chilling at the same time.
It's the first of many roles in which he makes an incredibly
arrogant character sympathetic.
Also starring: Karl Malden, Eva Marie Saint, Andy Griffith
