Sunday's At Tiffany's was originally a novel written by James Patterson. The novel comes to life in movie form as a Lifetime Original Movie. The two main characters are Jane, played by Alyssa Milano, and Michael, played by Eric Winter. The story begins with Jane as a young girl who leads an unhappy and affection-less existence with her mother. Jane's mother, Vivian, is too busy with her job in the New York theater scene to bother with Jane, except for Sundays. Every Sunday Vivian takes Jane to Tiffany's for a treat. Little does Vivian know, but they have a guest tagging along with them each Sunday and everywhere they go: Jane's imaginary friend, Michael.
Michael is Jane's saving grace. That is until the day he abandons her on her 10th birthday. Michael has no choice, but Jane is heartbroken to be without Michael and left alone to deal with Vivian. We end up flashing forward 20 years. Jane has become a playwright who works for her mother, and she is engaged to a professional actor. Something is not quite right in Jane's relationship and in her entire life in general, and yet she continues with the status quo because she thinks that this is what she is supposed to do.
One day her imaginary friend Michael shows up and turns Jane's world upside down. Jane refuses to believe that it is really him at first. Finally she accepts that it is, and she lets Michael stay at her place. She is trying to help him at the same time that he is trying to help her. Michael is helping Jane with her wedding planning because Jane's fiancÚ is always too busy to be bothered. During all of Michael and Jane's bonding, some heavy feelings arise that are not the same types of feelings they had for one another when Jane was a little girl. Who will Jane choose? Will Michael be able to stay this time? Only time can tell.
