That ’90s Show has brought back an old That ’70s Show character, and it looks like she is officially the series’ Laurie Forman replacement. After three installments, it’s unlikely that Laurie herself will make an appearance. While actor Christina Moore could feasibly make a cameo, the late Lisa Robin Kelly originally played the role. This makes bringing Laurie back for the Netflix spinoff a little more complicated, but the trouble might not be necessary.
