I haven’t watched it yet, but am posting it anyway, because I think there are some folks who'd like to have known of it, here..."From The Doctor to my son Thomas" is a viral video recorded by the Scottish actor Peter Capaldi (pictured) and sent to Thomas Goodall, an autistic nine-year-old who was grieving over the death of his grandmother. Thomas's father Ross posted the video to YouTube on 6 November 2014 so that his whole family could see it, but the video had wide appeal, and was viewed more than 200,000 times over the next 48 hours. Less than a week later it had over 900,000 views. In the video Capaldi portrays his character, the Twelfth Doctor, from the BBC science-fiction series Doctor Who. His message had a positive effect on Thomas; the father said the boy smiled for the first time since learning of his grandmother's death, and gained the courage to go to her funeral. The video was praised as a deeply affecting piece in The Guardian, The Daily Telegraph, The Independent, Hollywood Life, and various Spanish and Dutch publications, and by CNN and MTV News. It also had a positive impact on many viewers who suffered from autism and other mental health problems.
