Scottish actor James McAvoy has refused to back either the pro-independence or pro-Union camps in the forthcoming referendum, however warned that there was "no way back" after the vote.
Speaking on HuffPost Live on Wednesday, the X-Men star bemoaned the "political bickering… between both camps", adding that he didn’t want to "back either" even though he knew which way he was going to vote.
"I won't divulge partly for career preservation," he said, adding: "I don’t want to get behind politicians. Just because they’re talking about something really important, doesn’t mean they are trustworthy… and this is a humongous thing.”
McAvoy, who is currently promoting the film The Disappearance of Eleanor Rigby, did warn that the outcome of the referendum would likely be permanent.
"This is the first time in years a developed country has talked about splitting up and it’s a massive thing," he said. "If you vote for a president or a prime minister based on political or economic issues and they don’t deliver, that’s not so bad – you can protest four years down the line and vote them out. If you vote for continued unification or independence there is no protest vote – that’s it. And that could be it for decades, for centuries."
The 35-year-old, who was born in Port Glasgow, suggested that some Scots might vote just because politicians tell them they’re going to be "better off", but for him it was a "matter of the heart and a matter of personal identity and national identity".
"Am I going to look back and think ‘I voted because I thought I’d be a bit better off or I was going to get some oil, or did I vote because I believe in Scottish identity and Scottish independence’?" he said. "That’s way more important than the political or economic arguments. Independence or unification is here to stay forever."
A Better Together spokesperson said: "James McAvoy has kept his views private, which is his right, but he was completely right to point out that this is not like a normal election, where we can change our mind in four years. If we vote to leave the UK, it will be forever and there will be no going back. It is simply too important to risk on a protest vote.
"We don't have to be a separate nation to be a better nation. we can have what the majority of Scots want - more powers for Scotland without taking on all of the risks of independence. It's the best of both worlds. We should say No Thanks to separation on 18 September."
In August McAvoy nominated Alex Salmond and Alistair Darling to take part in the charity Ice Bucket Challenge - which both men accepted. Undertaking the challenge, Darling also highlighted the awareness raising website set up by Better Together's director of research Gordon Aikman, who has motor neurone disease.
