Hi. All I can remember of this movie is: takes place in present day, location is in a city, main characters are a man and woman (I think) who end up falling in love, but the odd thing is that every so often the action is interrupted so that you can see these hidden characters who appear out of nowhere to construct reality so the the earth/universe can continue. Then they disappear until they need to build something again. I remember thinking – too bad this turned into a love story, it’s such an interesting idea. What is this movie?
