A terminally ill boy was given a boost when he received a personal video message from Doctor Who.
Actor Matt Smith, 31, recorded the clip for four-year-old Jack Robinson, who is in hospital with an inoperable brain tumour.
After singing the Doctor Who theme tune, Matt announced: "Jack! Hello, Matt Smith here. Listen I am in Austin in Texas but I wanted to say hello as I've heard you are the biggest fan of Doctor Who in the whole wide world and I like Doctor Who fans.
"I have a friend called Jack and so I like Jacks. So, hello! Hello Jack! As I say, I'm in Austin and I'm sorry that I can't be there to come and say hello but when I'm back in England I'm going to try and come and say hello, my man, and give you a thumbs up and a what's up and see what you know about Doctor Who.
"I do hear that you are the biggest fan ever. Keep enjoying Doctor Who. I'm going to try and send you some stuff. I'm thinking of you mate. Lots of love."
Matt quit his role as Doctor Who last year and was succeeded by Peter Capaldi.
Jack, from Denmead, near Portsmouth, Hampshire, was diagnosed with an inoperable brain tumour and has been given only a five per cent chance of survival.
He showed signs of feeling sleepy and tired on January 17, and was rushed to hospital the following day, where he has stayed since.
A CT scan found a brain tumour and Jack was rushed to Southampton General Hospital to have a life-saving operation. He had five hours of surgery, where doctors were able to remove 40 per cent of the tumour.
After six agonising days of waiting, specialists concluded the rest of his tumour was inoperable.
Now he is being treated with chemotherapy and radiotherapy to make his quality of life better.
Since being diagnosed, friends and family have rallied around to make his final wishes come true.
This included meeting Take That singer Gary Barlow last week. So far, £7,000 has been given to the family, but the figure is likely to be higher, as funds are still being collected from different events.
Jack's dad Terry, 47, said: "Jack had gone to sleep, but we woke him up to show him the message. His eyes just lit up and he was so delighted - it made his day and he was over the moon.
"Gary Barlow tweeted he had a message from Matt Smith, but we didn't expect this, thank you Gary.
And thank you to Hollyoaks actor Darren Langford, a well-wisher, who said he had also been in contact with Matt.
"We're not sure which person he responded to, but we are grateful that he has."
