Movies Similar to Perry Mason: The Case of the Unwelcome Well (1966)

This episode is a virtual dry-run for the 1970s series Dallas, except that the question posed is not "Who Shot J.R.?" but instead "Who Killed J.K.?" There is no shortage of suspects when nasty oil tycoon Jerome Klee (Wendell Corey) is murdered, but the police finally settle upon Klee's foreman Allen Winford (James Best), who had been trying to prevent Klee from cheating an impoverished farmer named Jason Rohan (Paul Brinegar). Of course, Winford is innocent--else why would Perry Mason (Raymond Burr agree to take his case? ~ Hal Erickson, Rovi
