Jenna-Louise Coleman has spoken to the BBC about Matt and his departure from the show:
"I could not have imagined coming into the show without Matt as my Doctor, holding my hand, really, quite literally. I totally lucked-out in having a creative, generous, clever, and lovely fella to work alongside day after day.
I feel so privileged to have been part of Matt's reign, to have to been companion to what is and what I think always will be one of our greatest Doctors.
He is so in love with the show, he works tirelessly hard, surprises me every day, always creating and discovering something new about the Doctor. A true gent, a leading man and a very special friend.
I know it will be a very difficult goodbye for me, but I for one can't wait to see where his career takes him next. And of course with the same welcome I was brought in with, I look forward to welcoming the next Doctor. BUT it's not over till it's over. See ya at the big 5-0!"There will be a special video message from Matt to the fans sometime today.
