One of my favorite movies of all time is 'Big' with Tom Hanks and our Birthday Boy, Robert Loggia.  It's a sweet movie from the 80's that really holds up well.  It also has one of the most famous dance scenes in movie history...

According to Robert Loggia, when he and Tom Hanks filmed this scene at FAO Schwartz, there were doubles on hand in case he and Tom couldn't get the scene right.  He said they then made sure that they did the scene right so the doubles wouldn't have to be used!
