I hadn't seen this movie since it was first aired on TV in the early '70s; 30 years later, it is much better than what I recalled. Glenn Ford is at his very best; actually, all of the actors are really great. The script as well as the photography are first class. In an era where we all look for enemies outside North America, it is appropriate to remind ourselves that there might be enemies within. I wish WB would release this movie on DVD.
