David Tennant is recovering quite well from his back injury and could even be back performing in his Shakespeare play before it ends in January.
The Doctor Who actor is currently starring in Hamlet in London, but he was forced to pull out when he slipped a disc - a nasty back injury.
The star told BBC radio that he would "do his best" to get back on stage.
Filming also starts on the Doctor Who 2009 specials in the new year, and David hopes to be fit for that too.
David told the radio show: "It's supposed to be a six-week recovery period but I seem to be doing quite well so we'll keep monitoring it."
"But obviously I've got to do what I'm told," he added.

The London run of the Hamlet play is due to end on 10 January, so David will have to get better fast if he's to go back before the final performance in the capital.
David had an operation for his injury on 11 December.
He revealed that his back had been getting worse and worse, until one day in early December when he "woke up one morning and I couldn't really walk any more".
