The Professor (2018)

Johnny Depp stars as an English professor for a prestigious New England college named Richard Brown who learns he has late-stage lung cancer and probably only six months to live without treatment, which he doesn't plan on seeking.  On top of this, Richard is also a terminally bored, self-absorbed jerk whose own life has been falling apart long before this diagnosis. His wife (Rosemarie DeWitt) is cheating on him, with the chancellor at his school (Ron Livingston), no less. Now he can say whatever he feels like, knowing he's on his way out, and what he has to say is not always kind.  With perhaps only months left, he decides to continue to teach his literature class, hoping to impart some actual value to his current crop of students before he succumbs to the disease. He's also going to try to experience life without worrying about the consequences - a life he comes to realize he should have been trying to live all along.
