To celebrate National Letter Writing Day, Benedict Cumberbatch teamed up with a number of other celebrities (including Annie Lennox and Russell Brand) to pen a letter to Father Christmas. You may remember that the Sherlock actor gave a memorable speech earlier this year where he addressed the humanitarian refugee crisis in Europe. The thought-provoking video went viral and again, in this letter to Santa Claus, Benedict asks people to think of the many children who have been affected by something far beyond their control. His requests is that children should have more time "to be children" and allow them distraction from a "world gone mad". Featured on The Huffington Post, here is the text in full: Dear Father Christmas, So my friend has asked me to write to you... I have to confess it's been hard to know what to say. Mainly because like most adults I feel preposterous asking anything of you because our time with you is surely done. This is what I'd like to ask you to help with. A little more time for children to be children. Stretch the moment of magic and playfulness. Distract them from the realities of a world gone mad so that they can laugh with their breath rather than sob with their tears. Especially those caring for family members, or suffering illness, hunger or poverty. Especially those hiding in buildings as bombs rain down, or being handed shaking with fear or cold into a boat to escape environmental disaster or war. Please help to light up their worlds with a moment of joy and hope. Now we get our own presents, control our own fates, take responsibility for our own actions, and live in the world we have created... so it's not for us to turn around and plead for your help with the environment, the migrant crisis, the NHS, education, food banks, human rights, fundamentalism and wars. Though God knows we need all the help we can get with all these man-made problems and more. And it's not that you aren't compassionate and full of joy. You're great. In spite of you being changed into different colours for corporations and being bastardised to represent materialism gone mad - despite probably originating in some season based pagan druid ritual a million thought miles from requests for spontaneously combusting hoverboards... Kidadults cynically pointing this out after having their moment of belief in you are wasting everyone's precious time. Because you are not for them. You are for the children. Children who need some magic in a world were the borders between innocence and responsibility, playful imagination and cold, adult obstacles are continually shrinking. When I think about it you've got it tough this year... And when I really think about it I'm not sure that asking you for a lightsaber and getting one (not that I ever did by the way) is equatable with controlling the space time continuum and making the good of childhood last a little longer. But you do inspire wonder and awe amongst those that write you letters and go to sleep hoping there might be a new object in their possession come dawn. You inspire good behaviour and, at least in my memory, some desperate last minute attempts to redeem bad behaviour so as not to be overlooked. Spare a thought too for those millions who want to write to you but through illiteracy can't. Hear their words and help to give them the time and chance to learn how to read and write so they can better their lives and escape their impoverished beginnings. I feel a little sorry for you. And I guess I've done exactly what I said I wouldn't... Asked you to help with adult problems and solve some of the greatest worries we have for our children. I promise to leave some extra port and mince pies for you! Lots of love Benedict x P.S. Please could I have that lightsaber now?
