As reported by doctorwhonews.net, one of the Doctor Who restoration team has unearthed a rare treasure in the form of a 3 minute interview that William Hartnell gave in 1967 while appearing in a panto production of Puss In Boots, less than 3 months after his final outing as The Doctor. It is currently the only on-screen interview with Hartnell known to exist, and rather fittingly, it will be included as an extra on the upcoming DVD release of The Tenth Planet.
