A SCOTS actor is showing his support for a fundraiser set up for a young Celtic fan to receive life-changing treatment in America. 

Four-year-old Rory Gallagher has cerebral palsy and despite doctors telling his parents he would never be able to walk or talk, the Hoops supporter is defying the odds and taking each hurdle one step at a time. 

His journey has received attention from hundreds of thousands around the world - including Scots actor Martin Compston.

The Wee Man and Line of Duty star shared Rory's story with his followers and even offered to pay for the new Celtic strip.

Rory is now able to talk and in a touching video posted on his official fundraising Twitter page, he is seen rising out of a chair and standing - using only a walking frame for stability.

The post accompanying the amazing video tagged Celtic Footbal Club in the hopes of raising awareness for the Irish youngster's plight and said: "Rory's standing up 2 cerebral palsy he won't give up on his wish to walk @celticfc can u help us make Rorys wish come true #TeamRory"
