I met Matt on Ruby in the smoke,he was a very nice,polite & humble young man with excellent acting skills - watching him doing retakes was great to watch for every take he always added something different to the acting compared to the previous take,unless it was for a different camera angle for the same scene then he would repeat his mannerisms,tonality and posture identically everytime.
Sadly i missed the second part of the Sally Lockheart mysteries over christmas.
I think Matt will make a good Doctor Who,the best is yet to come regarding the show now Mr Moffat has his hands on the reigns and alot scarier too i imagine if his previous Who episodes are anything to go by
"The Empty Child"/"The Doctor Dances" (Series 1)
"The Girl in the Fireplace" (Series 2)
"Blink" (Series 3)
"Silence in the Library"/"Forest of the Dead" (series 4)
Pete said it best regarding the previous casting choices and they proved most Whovians wrong.
Heres a promotion picture with me in it for Ruby in the smoke
