Timeless (2006)

The penultimate episode of "Night Stalker" was one of a handful dumped onto iTunes in 2006. In this episode we get the return of Titus Berry (played by Stephen Tobolowsky here and Wally Cox in The Night Strangler) as Carl and the Scooby gang chase down a "vampire" who eats three pituitary glands every 35 years in order to extend her life.
