The movie is "The Lake House" (click here
I think the most appealing thing about this movie is that is speaks to one of our most widely-held beliefs about Twin Souls, which is that we must undergo a series of difficult trials in order to be together. In my belief system, Twin Souls need to become balanced between their mortal and divine selves, and their male and female personality characteristics, before they are ready to join. I think "The Lake House" showed how both characters had to overcome their primarily left-brained way of thinking (male essence) and open to the mysterious, to their heart-center, to their female essence.
So, take an evening to enjoy this movie. And listen to how Christopher Plummer uses his voice --brilliant!
