First, there is "Bundle of Joy", starring Debbie Reynolds. It's a Romantic Comedy Re-make of the Ginger Roger's Movie - "Bachelor Girl". (By the way, it is Debbie Reynold's Day on TCM!)
Then, there is a favorite movie of mine... "While you were Sleeping", starring Sandra Bullock. I remember seeing this in the theater when it firsy came out! I've always loved it... fun and cute Romantic Comedy! And, there is a bit of Christmas in it, too!
