Mary-Kate and Ashley Olsen
The twins played Michelle Tanner in the classic TV show Full House. The show was rebooted on Netflix as Fuller House, but without the stars of the show. Neither of them has been in the acting world since they were teenagers. Mary-Kate was allegedly somewhat open to the idea, but the timing was bad. Ashley fully did not want to come back. John Stamos said, "I remember trying to get them on Fuller House and they didn't want to come in or there was some miscommunication, or whatever it was... It was blown out of proportion."
