The popularity of That '70s Show in 1998 made the cast rich, but one star, Danny Masterson, was found guilty of a horrific crime, tarnishing his legacy. Ashton Kutcher and Mila Kunis, who became close friends with Masterson during the show, have remained in touch with him. Despite Masterson's guilty verdict, Kutcher and Kunis wrote letters in support of him during his sentencing, describing him as a role model and praising his character. They have not publicly cut ties with Masterson.
