From Wipikedia:
Ripper was originally a proposed television show based upon the character of Rupert Giles from Buffy the Vampire Slayer (created by Joss Whedon). More recent information has suggested that if Ripper were ever made it would be a TV-movie or a DVD-movie.[3] Giles, played by British actor Anthony Stewart Head, was nicknamed 'Ripper' while he was dabbling in the occult during his rebellious youth.
Whedon said that the show would be in the tradition of "classic English ghost stories" and would explore the theme of loneliness. Head described the idea as being like "Cracker with ghosts";[4] Cracker was a successful and critically-acclaimed British television drama about the work of a criminal psychologist that had run on the ITV network in the early 1990s. Whedon elaborated on some the themes he had planned for the series: "The people who live there, it's all very isolated. [Giles] himself has been gone for many years. He was surrounded by a de facto family that he no longer has. And [he is] sort of picking up his life all alone, and then getting involved in the underbelly of other people's lives, and finding out all about them. Loneliness is what I think of. It may not be the theme so much as the emotional intent of the series, but that's what really attracts it to me the most"[5] It was later reported that Whedon had written the two-hour pilot, and that Espenson and other Buffy staff writers had penned story outlines for other potential episodes.[6]
Originally in 2001, the show was planned to be aired as a miniseries on the BBC. Later mentions suggested a TV movie, however in an interview in December 2005, Head suggested that Ripper would be a "two hour movie, that might become part of a series of [Buffyverse] DVDs".[7] Whedon is presently involved in Goners, Runaways, and Buffy Season 8, so as of 2007, there are still no concrete plans for Ripper.
At Comic Con 2007, Joss Whedon confirmed that talks were almost completed for a 90 minute Ripper special on BBC,[1] with both Head and the BBC completely on board.
