Representing the swan song of Spencer Tracy and solidifying Sidney Poitier's resume, Guess Who's Coming To Dinner is an examination of the changes going on during the mid to late 1960's. The film has a very basic premise in which young Joey (Katherine Houghton) comes home from a trip to Hawaii with John Prentice (Poitier) to meet her parents (Tracy and Katherine Hepburn). What follows is the conflicted feelings that go along with the changing times of the 1960's. John will not marry Joey without the consent of her parents. Her parents are unsure about giving consent, not due to their own racism, but due to the fear of how difficult their life will be as an interracial couple. Added in are the two cents of everyone around the family. True, this can be a comedy at times, but it's more a look at the old guard facing the new guard. Directed by the legendary Stanley Kramer, the film represents a kind of social experiment. Let's drop '60's progressivism on the nuclear family of the 1950's (although the privileged life of the Drayton's is far from nuclear). The Drayton's are not conservative minded individuals, but very left leaning. Still, they fear for their daughter and how that current state of the world would react to them. Tracy delivers his final performance with a flourish and considering his death was imminent brings even greater power to his role. Add to the fact that this is one final pairing with Katherine Hepburn makes it even more bitter sweet. Hepburn also mesmerizes on the screen as the mother giddy over her daughter's upcoming nuptials, yet fearful at the same time. Once again Poitier proves that he is one of the greatest actors of this era, a witty and likeable presence that thinks things out for the protection of others. The only real negative of the film is Houghton's performance as Joey, which comes across as very snotty and annoying. Whether it was written this way or not, you can almost feel like maybe John would be better of with not being tied to her in some instances. I asked myself a question while watching this film. Have we moved forward in the last half century compared to our ideals? In some ways we have. Interracial marriage is not illegal in seven states, as the film reminds us. There's very little stigma related to it anymore, other than the old school and uneducated. The thing is that it feels like where we have progressed as a society, we're still slipping in other areas. To avoid making this review an ideology discussion I'll stop there. Guess Who's Coming To Dinner is a time capsule of the '60's and represents one of the greatest psychological battles of all time. When your ideals come home how are you going to react?
