John Clark Howat was an American film and television actor.

Dragnet is an American crime drama television series starring Jack Webb and Harry Morgan which ran for four seasons, from January 12, 1967, to April 16, 1970. To differentiate it from the earlier 1950s Dragnet television series, the year in which each season ended was made part of the on-screen title—the series started as Dragnet 1967 and ended as Dragnet 1970. The entire series aired Thursdays at 9:30–10:00 pm (EST) and was directed by Jack Webb.
