Actor-Shared Background: The story that Billy Crystal tells about his "best day" of going to a Yankee game with his father is a true story from his childhood. He notes at one point that, "I still have the program." Not only does he really still have it, but he got Mickey Mantle to autograph it twice: once at the game that day and once again some 20 years later on a talk show they were both guests on.
California Doubling: The opening scene in Pamplona was shot at Universal Studios in Universal Coty, California.
Completely Different Title: The movie's title did not easily translate into foreign languages. In France, it was called, "La Vie, L'Amour, Les Vaches," literally "Life, Love, and Cows." In Greece it was "Ti ekanes baba stin agria dysi?" which means "So what did you do in the Far West, Dad?"
Missing Trailer Scene: Some trailers feature a scene where someone's spurs are caught on a rail, but this scene is not in the movie.
No Stunt Double: Billy Crystal performed all of his own stunts, most notably, when he loops the rope around the cattle's head, and Curly whistles, making the cow take off, dragging Billy Crystal behind.
The Other Darrin: In the Latin American Spanish dub of the first film, Phil Berquist and Barry Shalowitz were voiced by Marcos Patiño and Eduardo Borja, respectively. In City Slickers 2, they were replaced by Mario Castañeda and Miguel Ángel Ghigliazza, respectively.
Real-Life Relative: Mitch's daughter is played by Billy Crystal's real-life daughter Lindsay. Her older sister Jennifer appears as a jogger in City Slickers 2.
Robin Williams was considered for either Mitch Robbins, Phil Berquist, or Ed Furillo. But he was already committed to Hook.
Rick Moranis was supposed to play Phil, but declined the offer to take a break and care for his wife Ann, who was very ill at the time (she died shortly thereafter and Moranis semi-retired from acting to take care of his children).
According to Billy Crystal, Charles Bronson turned down the role of Curly in an unseemly way which he reveals in his 2013 book Still Foolin' Em. Harvey Keitel also auditioned, while Clint Eastwood was considered, but wanted way too much money than the budget could afford.
