The BBC news website reports that David Tennant should be fit enough following his surgery to start filming the first of the specials on January 19th. Hurrah!
http://news.bbc.co.uk/1/hi/entertainment/7789916.stmDavid Tennant is expected to be fit enough to start filming scenes for a Doctor Who special next month, just weeks after surgery on his back.
The show's executive producer, Russell T Davies, said he was "hopeful" Tennant would start filming on 19 January.
"We'll have to be very careful," he said. "I don't think we'll be swinging him on a wire on his first day back."
