An underrated comedy gem, seemingly forgotten about by many people.
The first thing you may notice about the film is that Bill Murray goes against type here and plays a reclusive man who seemingly can't exist without his psychiatrist. Although Murray is great with his usual "charming, wisecracking, smarmy everyman", it's refreshing to see him do something different this early in his career.
What really makes the film work, though, is the relationship between Richard's character and Bil's character. What starts off as simple annoyance on Richard's part in relation to Bill becomes a homicidal rage. It's like taking a comedy plot from the 50's from a comedy duo and re-using it in the 90's but making it darker.
With a great supporting cast to boot, this movie is one of the better films back when Bill Murray focused on comedic films.
