From TVSeriesFinale.com:

Whedon has now announced that a 90 minute Ripper TV movie is in the works with the BBC. Whedon said that Head is on-board with the project and this was confirmed on the actor's website. The movie is expected to be filmed in England where Head and his family reside.

I have no words.  Just lots and lots of squeals.
