* DyeingForYourArt: Lloyd's chipped tooth is real - Jim Carrey had chipped his years previously, and had it uncapped for this film.
** Jeff Daniels also got his hair naturally frizzy that way by not conditioning, blow drying, or combing his hair for two months.
* HeyItsThatGuy
** You might recognize Mike Starr, aka Joe "Mental" Mentalino, in gangster or prison movies where he played virtually the same character.
*** ''Or,'' as Georgie Weiss, a [[{{Understatement}} cranky]] producer in ''Film/EdWood''.
** Nicholas Andre was played by former ''SaturdayNightLive'' cast member Charles Rocket (from the 1980-1981 season, which was considered one of ''SNL'''s many low points). What's funny is that JimCarrey auditioned to be on the 1980-1981 season and was passed up in favor of Rocket.
* OneSteveLimit: Averted out-of-universe; actress Karen Duffy oddly played two characters named Shay that year, in this film and ''Film/BlankCheck''.
** Averted also with Jeff Daniels, who played two characters named Harry in 1994, the other being in ''Film/{{Speed}}.''
* PlayingAgainstType: Jeff Daniels was not a comedic actor before he made this film, but the Farrelly Brothers convinced the studio to let them have Daniels in their movie when they watched ''Something Wild".
* RomanceOnTheSet: Jim Carrey and Lauren Holly married after meeting on this film, but it lasted less than a year.
* ThrowItIn: Jim Carrey threw in quite a bit, like "We landed on the moon!" and even "the most annoying sound in the world" (with the latter, you can clearly see Jeff Daniels and Mike Starr trying to hold it together, bracing for whatever Carrey was about to do; [[{{Corpsing}} Daniels fails and loses his shit]] right before it cuts to a close-up of Starr).
** Also, "Big Gulps, huh? Well, see ya later!"
