Take This Waltz is the story of a woman who's always looking for something new to fill the perpetual void in her life. Take This Waltz stars Michelle Williams, Seth Rogen, and Luke Kirby. Michelle Williams is Margo, a 28-year old who is in a loving marriage with Lou (Seth Rogen). On a plane trip home she runs into Daniel (Luke Kirby) and strikes up a flirtation with him, which is made unsettling by the realization that he has recently moved in directly across the street from her. It's a contrived premise, but Sarah Polley, the writer and director is wise to quickly move away from that set up and begins her focus on the study of Margot and her internal conflict.
This is a movie that will keep you thinking long after it is over. For example, the film begins and ends with the same scene. It's with Daniel. Until this point, and without our knowing it, the entire film is a flash back. The audience has been in the gap with Margot along. And yet there is more. In the film's final scene we see Margot again on the Scrambler amusement park ride—this time she rides alone and not with Daniel.
I recommend this movie.
