Welcome back to our “Then and Now” series (also called “What, This Again?”) where we compare and discuss a classic movie and one of its remakes. This week it’s the romantic comedy/thriller “Charade” and its 2002 remake “The Truth About Charlie.” Both movies have the same plot, of course: a young woman in an unhappy marriage returns to Paris to find both that her husband is dead and he was not who she thought he was. The original has Audrey Hepburn, Walter Matthau, and Cary Grant as the leads. The remake has Thandie Newton, Tim Robbins, and . . . Mark Wahlberg. Want to take a guess as to which is the better film? Well, don’t bother! Listen to us and we’ll tell you. Isn’t that easier?
