Movies usually age like milk. Especially message movies. But somehow, looking back at the cast of Guess Who’s Coming to Dinner, the whole thing feels weirdly electric, even sixty years later. It wasn't just a movie about a "difficult" dinner party; it was a high-stakes gamble featuring Hollywood royalty who were basically putting their reputations on the line. 1967 was a powder keg. Interracial marriage was literally illegal in many states until the Loving v. Virginia Supreme Court decision came down during the middle of production. Imagine that. You’re filming a scene about a black man marrying a white woman, and legally, in half the country, that’s a crime.
The weight of that reality sits heavy on the screen.
The Mount Rushmore of Acting
You've got Spencer Tracy and Katharine Hepburn. Honestly, it’s the ultimate screen pairing. This was their ninth and final film together. If you watch Tracy closely in this movie, he looks tired. He was. He was actually dying. He passed away just seventeen days after they finished filming. Hepburn knew it. The director, Stanley Kramer, knew it. They couldn't even get insurance for Tracy because his health was so bad, so Kramer and Hepburn had to put their own salaries into escrow as a guarantee. That’s how much they wanted this cast to happen.
When Tracy delivers that final monologue at the end—the one where he talks about what it’s like to really love someone—Hepburn is crying in the background. Those aren't "acting" tears. Those are the tears of a woman watching her partner of 26 years say goodbye to her through a script.
Then you have Sidney Poitier.
Poitier was at the absolute peak of his powers in 1967. He had To Sir, with Love and In the Heat of the Night coming out the same year. Think about that run. He was essentially the only black leading man Hollywood allowed to exist in that space at the time, which brought a massive amount of pressure. He had to be "perfect." His character, John Prentice, isn't just a doctor; he’s a Nobel-prize-level overachiever. He’s a widower, he’s polite, he’s brilliant. He had to be "beyond reproach" so the audience (which, let's be real, was mostly white at the time) would have zero excuse to dislike him other than the color of his skin.

The Supporting Players and the Newcomer
Katharine Houghton played Joanna "Joey" Drayton. She’s actually Hepburn’s niece in real life. People forget that. Her performance is often the one that gets critiqued because she's so bubbly and naive, but that’s the point of the character. She represents the idealism of the youth who didn't understand why their parents—the "liberals"—were suddenly flinching when the theoretical progress they preached actually walked through their front door.
But the real scene-stealers? The parents on the other side.
Beah Richards and Roy Glenn played John’s parents. Beah Richards, in particular, delivers this incredible, quiet power. There’s a scene where she talks to Spencer Tracy about how men, as they get older, forget what it’s like to feel that burning, irrational passion of youth. She basically schools him. It’s one of the most grounded moments in the film.
And then there's Isabel Sanford.
Years before she became "Wheezy" on The Jeffersons, she played Tillie, the maid. Modern audiences sometimes struggle with this character because she seems suspicious of John. But her perspective is fascinating. She’s looking at this brilliant black man and thinking, "You’re gonna ruin everything we’ve worked for by stirring the pot." It’s a complicated layer of internal community politics that the movie doesn't get enough credit for exploring.

What People Get Wrong About the Story
A lot of people think the movie is just a fluff piece today. It’s easy to look back and say it’s "dated." But look at the nuances of the cast of Guess Who’s Coming to Dinner and how they interact. The tension isn't between bigots and heroes. The tension is between people who think they are "good liberals" and the sudden realization of their own prejudice.
Matt Drayton (Tracy) isn't a villain. He’s a man who spent his life fighting for equality in his newspaper, but when his daughter comes home with a black fiancé, he panics. He uses "concern for their future" as a shield for his own discomfort. It’s a very modern kind of hypocrisy.
The Production Was a Secret
Stanley Kramer was terrified of protestors. He kept the plot under wraps as much as possible. They even used a fake title during early production to avoid attracting the wrong kind of attention. The atmosphere on set was a mix of intense mourning (for Tracy’s health) and intense purpose.
Cecil Kellaway, who played Monsignor Ryan, provides the moral compass. He’s the one who keeps poking Matt Drayton, reminding him that he’s being a hypocrite. Kellaway was nominated for an Oscar for the role, and you can see why. He brings a light touch to a movie that could have felt like a sermon.
The Impact on 1960s Cinema
When you look at the cast of Guess Who’s Coming to Dinner, you’re seeing the end of an era and the start of another. This was the "Old Hollywood" style—the big sets, the polished dialogue, the legendary stars—tackling a "New Hollywood" subject.

It was a massive box office hit. It proved that audiences were hungry for stories that actually dealt with the world outside the theater. It also solidified Sidney Poitier as the most important actor of the decade. He carried the weight of a whole race on his shoulders in every scene, and he did it with a dignity that is almost painful to watch when you realize what he was dealing with behind the scenes.
The Final Monologue: A Fact-Check
There’s a common myth that Spencer Tracy’s final speech was improvised. It wasn’t. It was written by William Rose, who won an Oscar for the screenplay. However, Tracy was so weak that he could only film for a few hours a day. The crew was essentially holding their breath every time he spoke. When he says, "You two are two wonderful people who happened to fall in love," he’s speaking to Poitier and Houghton, but he’s also speaking to the world.
It was the last thing he ever said on camera.
Actionable Insights for Film Buffs
If you’re going to rewatch this or see it for the first time, don't just watch the leads. Focus on these specific things to get the most out of it:
- Watch the background acting: Isabel Sanford’s facial expressions in the kitchen tell a whole second story that isn't in the dialogue.
- Track the lighting: Notice how Poitier is lit compared to the others. The cinematographer, Sam Leavitt, had to work hard to balance the skin tones in an era where film stock wasn't always optimized for black actors.
- Compare the two sets of parents: Look at how the Draytons (white) and the Prentices (black) react to the news. Both are actually horrified, but for completely different reasons. The Prentices are afraid for their son's safety; the Draytons are afraid for their social standing and "the way things are."
- Listen to the music: The score by Frank De Vol is purposefully light, which contrasts with the heavy themes. It’s a classic 1960s technique to make "medicine" movies go down easier for a general audience.
The cast of Guess Who’s Coming to Dinner didn't just make a movie; they made a statement. It’s not perfect—no movie is—but the sheer courage it took to make this in 1967 shouldn't be underestimated. You’ve got the greatest actors of their generation standing up and saying that love is more important than the "problems" of a prejudiced society. That’s why we still talk about it.
To truly appreciate the depth of this film, watch it back-to-back with In the Heat of the Night. You’ll see two completely different sides of Sidney Poitier’s brilliance and understand why 1967 was the year that changed Hollywood’s perception of race forever.
