Trivia: Wild Wild West
- Acting for Two: Kevin Kline as both Gordon and President Grant, including instances of Talking to Himself. Then there's the scenes where Gordon impersonates Grant and this gets really weird.
- Development Hell: Hoo boy. The film was pitched as far back as 1992 as a straight-laced film adaptation of the series, to be directed by Richard Donner (who had directed several episodes of the series) and with Mel Gibson slated to play Jim West. The duo ended up making Maverick instead. Tom Cruise was then attached to the project before he decided to revamp Mission: Impossible in its place; only then was the project overhauled into the comedic Will Smith vehicle you see today.
- Disowned Adaptation: Robert Conrad, who played Jim West on the original TV series, was very vocal in his dislike of the movie, personally accepting the Razzies it "won". His dislike started when they asked him to appear in the movie; on reading the script he described it as an insult to Ross Martin (Artemus Gordon) and Michael Dunn (Dr. Miguelito Loveless). You'd be hardpressed to find a fan of the show who disagrees.
- Executive Meddling: Producer Jon Peters' obsession with Giant Spiders, carried over from his previous meddling with Kevin Smith's script for Superman Lives.
- Fake American: Kenneth Branagh
- Hey, It's That Guy!: Gilderoy Lockhart is the Big Bad.
- Old Shame: Will Smith has since acknowledged how awful the movie was, especially considering he turned down the role of Neo in The Matrix to make this instead (though he's admitted that that part, at least, wasn't a mistake). He's been a little nicer to this film, however, in the wake of bigger disappointments like After Earth.
- Barry Sonnenfeld, Kevin Kline, Salma Hayek, and in fact half the staff at Warner Bros. feel the same way. Hayek in particular thought she was being underused, while Kline considered himself too good of an actor for the finished product.
- The MAD Magazine satire was called Mild Mild Mess.
