Ever looked at a vacation itinerary and felt a creeping sense of dread? That's the vibe. The 1969 film If It's Tuesday, This Must Be Belgium captured that specific, frantic energy of the "Nine Countries in Eighteen Days" bus tour better than almost anything since. It’s a cult classic for a reason. While the scenery is great, the real magic—the reason people still talk about it—is the chemistry of the If It's Tuesday, This Must Be Belgium cast.
They weren't just a bunch of actors thrown together. It was a weirdly perfect mix of old-school Hollywood, rising stars, and European character actors who looked like they actually stepped off a street in Rome or London.
The Anchors: Ian McShane and Suzanne Pleshette
Ian McShane plays Charlie Cartwright. Today, we know McShane as the powerhouse from Deadwood or John Wick, but back in '69, he was the ultimate charming rogue. He’s the tour guide. He’s the guy who has a girl in every port—literally. He’s cynical, fast-talking, and somehow still likable even when he’s clearly cutting corners.
Then you have Suzanne Pleshette as Samantha Perkins.
Honestly, Pleshette is the heart of the movie. She isn’t just a "love interest." She’s the audience surrogate. She’s the one trying to actually see Europe while everyone else is just trying to check boxes. Her husky voice and impeccable comedic timing make the romance with McShane feel grounded, even when the plot is total slapstick. If you’ve ever been the only person in a group who wanted to look at a statue for more than thirty seconds, you are Samantha.
The Eclectic Tourists
The If It's Tuesday, This Must Be Belgium cast succeeds because the supporting players aren't just background noise. They are specific archetypes that still exist on every tour bus today.
Mildred Natwick and Murray Hamilton (you probably remember him as the mayor from Jaws) play the bickering couple that provides the constant hum of domestic friction. Natwick, especially, is brilliant. She has this way of looking at a priceless cathedral like she’s checking the price tag on a toaster.

Then there’s Marty Ingels. He plays Bert Greenfield, the guy who is obsessed with getting everything on film. In 1969, that meant a bulky 16mm camera; today, it’s the person holding an iPhone on a gimbal and blocking everyone's view of the Mona Lisa. The more things change, the more they stay the same.
And we can’t forget Sandy Baron. His character, John Marino, spends the whole movie trying to find his Italian relatives. It’s a subplot that is both hilarious and weirdly touching. When he finally finds them, and it turns out to be a massive, overwhelming family that won't let him leave? That’s peak comedy.
A Who's Who of Cameos
One of the coolest things about this film is the "Easter egg" nature of the bit parts. You have some heavy hitters making brief appearances.
- John Cassavetes shows up. Yes, the legend of independent cinema.
- Vittorio De Sica, the director of Bicycle Thieves, makes a cameo.
- Anita Ekberg (the icon from La Dolce Vita) appears as one of Charlie’s many flings.
- Joan Collins even pops up.
It feels like the producers just called everyone who happened to be in Europe at the time and asked them to spend a day on set. It adds this layer of "cool" to what could have been a very standard studio comedy.
Why the Casting Worked for 1969 (And Now)
The late 60s was a weird time for movies. The studio system was dying, and "New Hollywood" was being born. This movie sits right in the middle. It has the polished feel of a big-budget travelogue, but the If It's Tuesday, This Must Be Belgium cast brings a gritty, improvisational energy that feels modern.
The humor isn't just about "look at the silly foreigners." It’s actually more about "look at the silly Americans." It skewers the "ugly American" trope but does it with a lot of affection. You realize that these people are rushing through Europe not because they don't care, but because they are desperate to experience everything and don't know how to slow down.

The film was shot on location. That’s a big deal. When you see the cast in London, the Netherlands, Switzerland, and Rome, they are actually there. The exhaustion on their faces by the time they get to the end of the trip? That probably wasn't acting. Dragging a film crew across multiple borders in the 60s was a nightmare.
The Legacy of the Ensemble
If you watch modern ensemble comedies—think things like The White Lotus or even the National Lampoon’s European Vacation—you can see the DNA of this cast. They set the template for the "clashing personalities in a confined space" genre.
The chemistry between McShane and Pleshette is the glue. Without them, it’s just a series of vignettes. With them, it’s a story about two people who find a genuine connection in the middle of a chaotic, artificial environment.
What Most People Get Wrong
People often dismiss this movie as a dated "boomer" comedy. They think it's just about old people on a bus.
Wrong.
It’s actually quite cynical about consumerism. It mocks the idea that you can "buy" culture in a 45-minute stop at a gift shop. The cast plays these moments with a lot of nuance. When Murray Hamilton’s character is more worried about the exchange rate than the Colosseum, it’s a sharp critique of American priorities at the time.

Actionable Takeaways for Movie Buffs
If you’re looking to dive into this era of cinema or just want to appreciate the If It's Tuesday, This Must Be Belgium cast more deeply, here is how to do it:
- Watch for the Background Actors: Many of the "tourists" in the wide shots were local extras who had no idea what was going on. Their genuine confusion at the American actors' antics is gold.
- Compare McShane to His Modern Roles: It is wild to see the man who became Al Swearengen playing a lighthearted, cheeky tour guide. It shows his incredible range.
- Check Out the Soundtrack: Donovan wrote the title song. It perfectly captures that late-60s "jet set" vibe.
- Look for the Location Gaps: If you know European geography, you’ll notice the bus route makes absolutely no sense. Part of the fun is realizing that the "Tuesday" in Belgium might have actually been filmed in a completely different country.
The film remains a time capsule. It reminds us of a time when international travel was still a brand-new novelty for the middle class. But more than that, it’s a masterclass in ensemble casting. Every actor knew their role, stayed in their lane, and contributed to a chaotic, hilarious whole.
To truly appreciate the film, look past the 60s fashion and the dated jokes. Look at the eyes of the actors. They are portraying that universal human desire to belong—even if that means belonging to a group of strangers on a bus, desperately trying to figure out which country they are in today.
Next Steps for Classic Film Fans
If you enjoyed the ensemble dynamic of the If It's Tuesday, This Must Be Belgium cast, your next logical watch is The Out-of-Towners (1970). It offers a similar "traveler in distress" vibe but swaps the European bus for the chaos of New York City. Alternatively, look into Suzanne Pleshette’s work on The Bob Newhart Show to see her further refine the "grounded woman in a crazy world" persona that she pioneered in this film.
