True Confession was one of the unfunniest of the "screwball" comedies of the 1930s, and its musical remake, Cross My Heart, isn't much of an improvement. Betty Hutton steps into the old Carole Lombard role as Peggy, a compulsive liar who'll do anything to help her attorney fiance Oliver Clarke (Sonny Tufts) get ahead. When it looks as though an unsolved murder case will be Clarke's ticket to success, Peggy, sticking her tongue in her cheek (as she always does when she's about to tell a whopper), glibly confesses to the killing. Peggy's plan is to allow her boyfriend to prove her innocence, thereby cementing his reputation as a man of integrity-but things don't go quite as planned. The subsequent trial is enlivened by the antics of looney Russian actor Peter (Michael Chekhov), who may or may not be the actual murderer. Betty Hutton's song numbers are just about as mediocre as the rest of the film.
