It’s Glenn Ford day at TCM on tonight’s Summer Under the Stars tribute, and there are interesting films all day, including, at 4 p.m. ET, the classic 1955 inner-city school drama, Blackboard Jungle. But in prime time, pay attention to this rarely televised 1962 crime thriller, Experiment in Terror, in which Ford plays an FBI guy handling a case in which a man threatens to kill a woman’s younger sister, whom he’s captured, unless the woman steals money for him from the bank where she works. Lee Remick plays the bank employee – and her little sister is played by Stefanie Powers, who was then 19 years old.
