Melissa Joan Hart, the star of Clarissa Explains It All and Sabrina, the Teenage Witch, explains it all - onscreen and behind the scenes. Melissa Joan Hart explained it all-from dating to bullies-in her ground breaking role as Clarissa Darling on Clarissa Explains It All. She cast a spell on millions more viewers as Sabrina, the Teenage Witch. Now, in Melissa Explains It All, Melissa tells the frank and funny truth about her extraordinary past and her refreshingly normal present. From the moment four-year-old Melissa decided she wanted to be on television, she has shown a singular determination and focus-whether it's for booking three national commercials so her dad would build her a tree house or for nailing the Clarissa audition. And she never let fame go to her head. With one foot in Hollywood and one foot in reality, Melissa makes us laugh along with her as she talks about: guest appearances in shows like Saturday Night Live and The Equalizer; auditioning for Punky Brewster and Clarissa; her early Broadway days; wacky parties she's thrown and attended; the actors who influenced her and whom she befriended, worked with and competed against; her experiences both on off-set-with Sabrina's Salem the Cat and Elvis the Alligator on Clarissa; and, how she met the love of her life at the Kentucky Derby.
