No Time for Sergeants (1958) starring Andy Griffith
Technically, No Time for Sergeants is Don Knotts first movie. However, his time on-screen is very brief. He plays a neurotic Army officer who gives Andy Griffith’s character, Will Stockdale, one of his tests. As a consolation, however, No Time for Sergeants is a hilariously funny movie. The basic plot has Will Stockdale being drafted into the Army. Attempts by other recruits to harass the country boy fail miserably. Due to Will’s easy-going nature, lack of apprehension of some of the insults, and his incredible good luck.
