The Four Weddings and a Funeral star was among those left stunned by the referendum vote in June (16), when Brits opted to split from the European Union.

The decision prompted then-Prime Minister David Cameron to step down.

But Grant is optimistic his fellow Brits will see sense and reconsider before it's too late.

"If I had to put money on it I would be surprised if we Brexit," he told WENN. "Don't forget the referendum was only an advisory; it was not a compelling thing.

"I think it might be commonly fudged, especially now that people are starting to realise quite what a self wound it was."

Hugh also believes the Brexit vote was a wake-up call for "the fanatics of Europe, who wanted more and more of homogenised super state", adding, "They have realised countries really don't want that and they have had to back down on that, which is actually not a bad thing."

The actor put his Hollywood career on the back burner to concentrate on more political matters and reveals director Stephen Frears had to convince him to return for new movie Florence Foster Jenkins, in which he portrays Meryl Streep's husband.

"Stephen said, 'Let's do a film, go back to showbusiness, Hugh', and I always thought he was the drink talking," Grant jokes. "Then, one day, he sent this brilliant script and Meryl Streep was attached. I thought, 'I don't really want to do more acting, but this is such a good project and so classy I can't say no'. So I said yes and I'm very glad I did."
