Trivia[]
- The two Normandy place names cited in the film are real: Morville sur Andelle and Le Heron, both tiny villages northeast of Rouen.
- The only Peanuts feature film to include adults on-screen and with speaking parts rather than the usual "wa-wa-wa" trombone sound.
- The château that Charlie Brown, Linus, and Snoopy stay in is based on the château that Charles M. Schulz was billeted at for six weeks in World War II. This is the Manoir de Malvoisine, near Le Héron. In the film, the estate is called Mal Voisin.
- This was the fourth and final Peanuts theatrical feature overseen by creator Charles M. Schulz.
- The TV special What Have We Learned, Charlie Brown? was the epilogue for this film.
- On May 7th 1980, "The Price is Right" taped a segment featuring a showcase saluting "Bon Voyage Charlie Brown" to be broadcast while the movie was still in theaters later that month. After showing a short clip from the movie (The scene on the plane with Snoopy eating and listening to headphones while hiding Woodstock in the ashtray every time the stewardess walks by) the first item offered is a three piece set of American Tourister luggage. Following this offered is a week long trip to London. Then, after mentioning that Snoopy visits Wimbledon in the movie, Johnny Olson offers a set of two tennis rackets a supply of tennis balls and tennis outfits. Then, mentioning that the Peanuts gang goes to the last leg of their trip in Paris, a week long Paris trip for two is offered. Following that Olsen notes that in Paris the gang rent a car which Snoopy drives - 'being the only one qualified to drive he takes them on the ride of their lives...and you'll have the ride of YOUR life in this new car from France!' - a 1980 LeCar. To top off the showcase a pass for the contestant and 24 of his/her friends to see a screening of the movie on the Paramount lot was offered. The contestant bid $8600, the actual retail price was $10,907 and he won when the other contestant overbid.
- When Linus screams as the château goes on fire, he has Charlie Brown's "scream" by Peter Robbins, first heard in A Boy Named Charlie Brown, and used as a stock "scream" for Charlie Brown (especially whenever he fails to kick Lucy's football) and the rest of the Peanuts gang in countless specials and all four "Peanuts" movies.
- The scene where Peppermint Patty and Charlie Brown share a desk was based off a previous comic strip when the roof collapses at Peppermint Patty's school and they're forced to attend Charlie's school. The part that wasn't recreated was when Patty and Charlie returned from the principal's office and were promptly sent back when Charlie objected to her speaking for both of them.
- This is the only Peanuts production where you actually see the adults; and they actually speak in something beyond the "Blah-blah-blah" muted horn gibberish that the adults in Peanuts cartoons usually speak in. Usually you don't see adults at all in a Peanuts cartoon; but in the opening to this movie you see the cab driver walk out in plain view of the audience out to the cab in front of the chateau. Later he runs in the field and shouts the word "fire" (in French). Again, it's rare for an adult to actually make an appearance in a Peanuts cartoon, and to speak in a language other that gibberish.
- This is the last Peanuts film to be distributed to Paramount before 20th Century Fox took over after the release.
- Peanuts became distributed to 20th Century Fox in June 1980 due to Peanuts Bon Voyage Charlie Brown (and don't come back) being the final Peanuts film to be distributed to Paramount Pictures, until 2018 when DXH would take over the rights.
- Unlike the first three feature length films, this one does not give on-screen billing to any of the Peanuts characters in the opening credits.
- In the scene where the Kids, Snoopy and Woodstock leave in their Rental Car after arriving in Paris, they are back ended. Marcie complains to the other Drivers in French with no translation, roughly translated she says, "What do you have in your head? Oooh, the horns! What do you want me to do? What a slab! The foot of nose! Do you want to rub us?"
