Adapted from a typically tricky J. B. Priestley stage play, Dangerous Corner is a cautionary fable about the damage caused by telling the unvarnished truth. A burned-out radio tube is the catalyst for a series of painful and potentially dangerous revelations during a weekend party. The upshot of all this is the suicide of party guest Ian Keith and the mysterious theft of a large sum of money. Through an ingenious last-act plot twist (of the kind so beloved by Priestley and his ilk), the audience is treated to both a happy and a tragic denouement. Long ignored by film historians, Dangerous Corner was rediscovered when it popped up repeatedly on the American Movie Classics cable service in the mid-1980s.
