A triple dose of "tough guy" flicks show Charles Bronson in three very different roles. In Cold Sweat (1970), he plays a drug trader who resorts to revenge to save his wife (Liv Ullmann). In Guns of Diablo (1964), he appears with a young Kurt Russell. And in Someone Behind the Door (1971), he plays a mysterious amnesiac who's made to believe that another man's philandering wife (Bronson's real-life love, Jill Ireland) is his own.
