The surprising Brexit victory, which followed after Britain voted to leave the European Union (EU), has left Hollywood celebrities in shock.

After 43 years in a historic referendum, the voters turnout was 71.8 per cent with a win by 52 per cent to 48 per cent as 30 million people cast their votes on Friday.

Expressing concern over the highest turnout at a British poll since 1992, British celebrities voiced their thoughts on Twitter.

Some expressed their dismay and many others came out in support. While Daniel Craig donned a Tee with the quote, “No man is an island. No country by itself,” and posted it on Twitter, here is what other celebrities said.

Harry Potter author JK Rowling mourned over the Brexit triumph.

"Goodbye, UK. I don’t think I’ve ever wanted magic more. Scotland will seek independence now. Cameron’s legacy will be breaking up two unions. Neither needed to happen," Rowling wrote in a series of tweets.

“If one more person tells me voting remain is for the rich: WHO WILL SUFFER IF THE EXPERTS ARE RIGHT AND 100K JOBS GO AND WELFARE IS SLASHED?” she also posted.

English darts player and presenter Bobby George wrote: “If the Capt says IN I’m IN. It’s up to you what you do but make sure you have your vote on Thursday @David_Cameron,” and declared that he will vote Remain.

Actor and TV host James Corden tweeted in support, “I can’t get my head around what’s happening in Britain. I’m so sorry to the youth of Britain. I fear you’ve been let down today."

Thor actor Idris Elba made his point clear in his tweet. “My parents immigrated to the UK, worked hard and made a contribution..ME…on that basis VOTE IN….#EUDebate,” he wrote.

Meanwhile, actor John Cleese indicated he would rather leave. "If I thought there was any chance of major reform in the EU, I’d vote to stay in. But there isn’t. Sad," he posted.

The Sandman creator Neil Gaiman, who was once a British native but resides in US now, wrote: "Dear UK, good luck. I am afraid you are going to need it."

Actor Hugh Laurie was wary as he posted a message for his fans. He wrote: "Congratulations exiters. Reverse is across and down, easy on the clutch".

Sadly, if it comes true, Britain would be the first country to leave the EU since its formation.
