This is the trailer for the movie Boulevard, which is the last live film that Robin Williams acted in before his death.
The film follows Williams as Nolan Mack, a bank manager who has had the exact same job for a quarter of a century. When Mack meets a male hustler, he is forced to confront his sexuality and examine the totality of his life.
Robin Williams committed suicide last August, triggering an outpouring of grief from his many fans. This film, upon first glance, seems like a fitting finish to an incredibly talented and moving career.
