Game of Thrones, Harry Potter and Trainspotting stars have joined more than 80 Scottish actors, artists and writers calling for the UK to stay in the European Union.
The group argue that that remaining in the EU would be good for Scotland - and for the arts,
Game of Thrones actor Daniel Portman, who plays Podrick Payne in the hit HBO television series, said that leaving the EU would be "like stepping in a time machine and going backwards".

Mr Portman, who plays a peace-loving squire on the show, also argued that a Brexit could lead to increased tensions on the continent and in the UK.
A so-called Brexit would give a boost to "the far-Right's politics of intolerance", he warned.
Author Val McDermid, who announced last month that she was backing a Remain vote, said that Scottish culture had long benefited from "sharing our creativity with our neighbours and developing strong links with European institutions, going back to the Middle Ages.
"Our culture has become richer, wider and deeper as a result."
The group admit that the EU is not perfect.
However, they say that the benefits of EU membership have included jobs, security and legal protection for workers in Scotland.
Many projects and collaborations in the arts would have been impossible without EU funding and free travel within Europe, they warn.
