Eric’s Sister Got Replaced Because Actress Lisa Robin Kelly Struggled With Addiction
Actress Lisa Robin Kelly originally played Eric’s older sister, Laurie. She struggled with alcohol abuse, however, and had to leave the sitcom in 2003 during Season 3. Kelly came back for a few episodes in Season 5, but she was ultimately replaced by Christina Moore at the start of Season 6. The troubled actress admitted, “With That ’70s Show I was guilty of a drinking problem… And I ran.”
Unfortunately, Kelly passed away at 43 in August 2013. The Los Angeles County coroner’s department said the actress died from drug intoxication.
