Supernatural fans, get ready for 'The Winchesters' prequel! The trailer has just been released, giving us a glimpse into the lives of John and Mary Winchester, the parents of Sam and Dean. Set years before their sons' battles with evil, this spin-off promises to be just as action-packed, drawing inspiration from mythology, religion, and urban legends. With show creator Eric Kripke involved in 'The Boys,' Jensen Ackles narrates and produces, and stars from the original show expressing interest in returning, this is not one to miss. Look out for its debut on October 11th on the CW.
