Jack Robinson is 4 years old, a huge Doctor Who fan, and has an inoperable brain tumor. No one knows how Matt Smith heard about the little Whovian, but according to Jack's dad, he loved the video. "His eyes just lit up and he was so delighted. It has made his day."
At the New Orleans Comic-Con, Matt Smith had this to say about the potential of future River Song episodes:
I'm really possessive over Alex [Kingston]. I said this to Steven [Moffat]. I was like, 'Listen, just don't! Just not Alex. Anyone else, but don't give [Capaldi] River.' But Peter is the Doctor now so hey, what can I do?"It's still unclear whether or not the Doctor's wife will return in Series 8. Is she all but a memory like on Trenzalore, or are there more spoilers we should look out for? We'll all just have to wait and see.
