As gripping as it is funny, Orange Is the New Black has become one of the most forward-thinking and revolutionary shows on television in just two years’ time. The new issue of Rolling Stone — on newsstands this Friday — features stars Taylor Schilling and Laura Prepon on the cover and no-holds-barred interviews with the cast, creator Jenji Kohan, and memoirist Piper Kerman, whose book inspired the series. Mac McClelland’s cover story explores all of the reasons why the series has become mandatory viewing – how it primarily features women in its cast, shines a light on gay and transgender issues and gives a voice to one of the most marginalized groups in America: prisoners.
