The controversial filmmaker appeared on Channel 4 news to plug his new film Fahrenheit 11/9, but took the opportunity to make a few anti-Brexit swipes during the wide-ranging discussion with anchor Krishnan Guru-Murthy.
Mr Moore claimed the UK had sacrificed “thousands of lives” to save Europe during both World Wars, as well as warning Britons would have to wait in a “long f***ing line” if they travelled to Paris via the Channel tunnel after Brexit.
The author pleaded with the UK not to leave Europe, telling Mr Guru-Murthy: “You can’t leave, I’m sorry! We’ve seen that Europe can’t do it without you. They need you as much as you need them.”
Mr Moore appealed to Britain’s past claiming: “Your history is not to pull up the gates and say ‘we’re an island now, we really are an island, we’re cutting ourselves off from everybody’.
“You can’t leave Europe, they’d be no Europe without you. You saved Europe. You sacrificed hundreds of thousands of lives to save Europe, not once but twice!”
He continued: “To think that this great country would want to then say at this point in the 21st century, nah, enough of that, we’re done.”
Mr Moore claimed that the European Union and the UK needed each other to “survive”.
He said: “We all need each other. The world is… we’re not going to survive. Whether it’s climate change. Whether it’s globalisation. Whether it’s all the things that have been going on.
“We’re not going to survive unless we realise we’re all in the same boat together.”
Continuing on his rant he used expletives as he warned that Britons would have to wait in line after arriving in Paris via the Channel tunnel.
Mr Moore said: “You get off that tunnel train after we’ve left Europe, you’re going to be standing in a long f****ing line in Paris.
“You’re going to spend half the day in Paris, standing in that same f***ing line that I have to stand in.
“Stay out of the line, stay in Europe and get your parties here to listen to you.”
