The only original main character from Full House who doesn’t make an appearance in Fuller House is Michelle, the youngest Tanner daughter. Michelle was played by twins Mary-Kate and Ashley Olsen on Full House, who made their acting debut on the show at just six months old. The twins alternated playing Michelle for the duration of the show until it wrapped with its eighth season in 1995. However, when the idea of a reboot came up, neither of the Olsen twins was interested in reprising their role as Michelle in Fuller House. This left producers with a difficult dilemma regarding Michelle’s character. However, while leaving Michelle out of the reboot altogether certainly solved a potential continuity issue, it was ultimately not the best decision for the series.
Even before production began on the reboot, producers should have been prepared for the Michelle issue. While it was said that Fuller House star and producer John Stamos was to blame for the Olsen twins’ absence in Fuller House due to his failure to reach out to them personally, the twins had already unofficially retired from acting by the time Fuller House was in the works. The fact that they’d barely acted since they turned 18 in 2004, focusing instead on building their fashion empire, is more likely the reason for their lack of interest in returning.
Since the twins weren’t on board, the producers of Fuller House considered recasting Michelle with Elizabeth Olsen, the twins’ younger sister who had become a successful working actress by then. Elizabeth would have been the perfect replacement for Michelle: not only does she bear a familial resemblance to the original actresses, but Olsen’s later work in Wandavision proves she would have nailed a family sitcom role like Fuller House. Unfortunately, the producers never seriously pursued this possibility, with the series’ creator Jeff Franklin claiming that it “was just an idea” and that they “were never going to recast the role.”
However, the Fuller House producers should have ultimately reconsidered their stance, since the character’s absence is a major plot hole in the series. Even if Elizabeth Olsen didn’t sign on, the reboot still would have been better off recasting Michelle with another actress who bears at least some resemblance to the twins. The character didn’t have to be a part of the main cast again, but she could have made at least an appearance or two over the course of Fuller House‘s five seasons in order to provide audiences with some closure and a proper explanation for her absence.
