David Tennant, the latest Dr Who took time out to talk to Breakfast this morning about his new role in a drama this autumn and his plans for future travel in the Tardis.
David Tennant on the set for the new drama 'Recovery'
David is currently filming for 'Recovery', a two-part drama about a couple who have to learn to cope after an accident in which he suffers a debilitating brain injury.
Our presenter Susanna Reid went to meet him on the set to find out about the new part he was playing and get his thoughts on the future for Dr Who.
David said his role in 'Recovery' had meant quite a bit of research. He had read about and met people who had suffered from brain injury.
"Each instance of brain injury is very unique, but you can get a general sense of what it might be through talking to people. You can't really imagine what it must be like to be married to somebody who becomes a different human being," said David.
Our brain is our personality, is our thoughts, is our world and if that gets knocked, even a couple of degrees sideways, you become something fundamentally different."
David confirmed he would be doing a second series of Dr Who next year. He said: "We had some great people in this last series. It seems to attract people from all spectrums of the acting world. We've got Peter Kay and we've got Pauline Collins and everything in between.
"I had a very good time last year and hope I have a very good time next year and after that, we'll see what happens."
