Since Lisa Robin Kelly (who played Laurie Forman on That ’70s Show) died in 2013, Redditor u/marie_g10 questioned how That ’90s Show might address Laurie’s absence. Other fans had many ideas about it.
u/Diseman81 pointed out that the creators could hire the other actress, who also played Laurie on That ’70s Show. While Lisa Robin played Kelly Laurie from seasons 1-5, here’s the real reason “That ’70s Show” recast Laurie Forman for season 6: Kelly’s personal issues interfered with her ability to stay with the show. During Season 6, Christina Moore played Laurie, but after Season 6, the character was mentioned but did not appear on screen.
u/MrsShawnHunter suggested a solution consistent with the way That ’70s Show dealt with Laurie’s temporary absence during Season 3 while she was at beauty school. In That ’90s Show, Laurie could have moved to Paris to pursue her dream of becoming a hairstylist. Also, u/MrsShawnHunter pointed out that Laurie’s character could have just died. There are certainly many reasonable explanations for her absence, but some fans would prefer Laurie’s character to continue even if her presence on That ’70s Show was unstable.
u/berrybunniez added that Lisa Robin Kelly was a talented actress who “breathed life into the show,” and that “That ’90s Show” will hopefully give her and Laurie at least a little nod, even if they don’t bring Laurie’s character back by another actress.
