A leading Hollywood studio is in talks with Arron Banks, the millionaire behind Nigel Farage's Brexit campaign, to make a film out of his referendum diary.

"We have had some very serious Hollywood people in touch with us who are going to buy the rights to the book," Andy Wigmore, spokesman for Banks, told the Telegraph. "They want to buy the option on it.”

Warner Brothers — the studio behind the Harry Potter franchise — is understood to "have done a bit of research," concluding that "effectively [the diary] is like a screenplay so half the work has been done for them," said Wigmore.

He confirmed the producers want to meet Farage and Banks when they are in the U.S. next month for President-elect Donald Trump's inauguration to discuss the idea further.

Banks' diary — called the Bad Boys of Brexit — details how he ran the Leave.EU campaign with Wigmore and the American pollster Gerry Gunster. Scenes would likely include the Battle of the Thames when a pro-Leave flotilla of fishing boats collided with one carrying singer Bob Geldof.

All profits would go to charity, said Wigmore, who explained that the film would be "a comedy."
