Ruby Sparks (2012)

Calvin is a genius novelist who begins to type a new novel on his manual typewriter about Ruby, his dream girl. He can't believe his eyes, because the next day, Ruby becomes a real person, and they begin to have a beautiful relationship together. If the relationship isn't perfect, all Calvin has to do is simply type the words on the page and Ruby's actions change to what he needs.—Douglas Young (the-movie-guy)
