The Show that Named Itself
The show was initially pitched with titles like "Teenage Wasteland" and later "The Kids Are Alright" or "Reeling in the Years". However, because both names were references to songs by The Who and Steely Dan, legal issues prevented their use. As a result, the show was eventually announced as "Feelin' Alright", but that name didn't catch on. After noticing that audience members in focus groups would say things such as "I like that '70s show" to describe it, they eventually decided to simply call the series "That '70s Show".
A True 70's Man
Tommy Chong, the actor who played Leo, was absent from the show from 2003-2004 while serving a jail sentence for selling "drug paraphernalia" (water pipes). He expressed surprise later that this wasn't written into the show's storyline since it fit his character so well. Interestingly enough, Tommy was cellmates with Jordan Belfort, and encouraged him to write his memoirs what later became the movie "The Wolf of Wall Street."
Who's the real FES?
Jackie constantly makes fun of Fez in the show for being foreign. In real life, however, the actor who plays Fez, Wilmer Valderrama, was born in the USA, while Mila Kunis was born in the USSR, in what is now Ukraine.
Not So Natural Blonde
Laura Prepon, a natural redhead, had to dye her hair blonde to star in the film "Karla" in 2006. As a result, her character Donna Pinciotti changed hair color for the show's final two seasons.
Fez, the Ladies Man
Fez was an awkward and often lonely character on the show, but Wilmer Valderrama had much better luck in his real personal life. He has dated numerous stars such as Mandy Moore, Lindsey Lohan, Avril Lavigne, Ashlee Simpson, and is currently dating Demi Lovato. Not bad!
It Was Meant to Be
Mila Kunis admitted that Ashton Kutcher was her first kiss, both on-screen and off! Though the pair made out multiple times onscreen, they didn’t get together until years after the show ended. Now that they're more distanced from "That 70s Show" and their professional lives have grown, they started dating almost in secret, but are now engaged and also expecting a child!
Friends Til the End
Laura Prepon said she “wasn’t surprised” by the fact that Ashton Kutcher and Mila Kunis were dating. When asked if she’d go to their wedding, she responded: “If Mila wanted us there, which she would because we’re family. We support each other.” How very Donna and Jackie… minus all the snark.
