"Power of Attorney" was a rare appearance on American television for veteran British Shakespearean actor Richard Johnson, cast in uncharacteristically villainous mode as professional swindler James Jarvis, who leaves his female victims penniless in 'love em and leave em' fashion. He pretends to invest a certain amount of their money, then claims bankruptcy, moving on to his next target, the wealthy Mary Crawford (Fay Bainter), who easily falls for his surface charm, but her younger companion, Agatha Tomlin (Geraldine Fitzgerald), is not so easily swayed. When Agatha decides to have the con man meet Mary's attorney, Jarvis resorts to murder to continue his misdeeds unopposed. The climax is most satisfying. Johnson was soon to play Bulldog Drummond in a pair of features inspired by the success of the James Bond series, while this turned out to be the final role for Oscar-winning (for 1938's "Jezebel") actress Fay Bainter, who died three years later at the age of 74.
