“The Girl on the Train” is based on Paula Hawkins’ bestselling novel of the same name and is adapted for the screen by Erin Cressida Wilson (Secretary) and directed by actor/director Tate Taylor who directed “The Help” and “Get on Up”. There’s plenty of talent there alone to entice you to the theatre this weekend but I’ll give you a few more good reasons to catch this somewhat complicated whodunnit; Emily Blunt, who is simply brilliant in her role, Haley Bennett and Justin Theroux. The story starts with introducing you to a girl on a train, Rachel (Blunt), more woman than girl in years but girl in behavior, as she tells you of the houses she passes each day and her curiosity as to what the lives are like within them.  She begins to more or less obsess over one particular couple in love, Megan (Bennett) and Scott (Evans), who reside in a house she wished she lived.  He is the sexy husband she desires to have and she is the beautiful young woman with whom she longed to be. Soon, we learn that she had once lived two doors down in a lovely home that is still occupied by her ex-husband, Tom (Theroux), his wife, Anna (Ferguson), and their baby. What led to her divorce may be what now leads her to occupy her mind with such things as what goes on in what she considers to be a more perfect life than hers; alcohol, her personal demon. She drinks heavily, on the train and off, and is paranoid,often blacks out and sees things that may or may not be actually happening, because of her drinking problem.Â
