Sacha Baron Cohen has said making Borat Subsequent Moviefilm was the "hardest movie to make" as a result of the risks taken by the cast and crew and recalled how he had a panic attack during filming.

The 49-year-old, who reprised his role as Kazakh journalist Borat Sagdiyev in the comedy sequel, admits that it was one of the riskiest films ever made with the cast and crew going to extreme measures to film particular scenes.

Speaking to The Guardian newspaper, he said: "It was the hardest movie to make that I've ever heard about. Maybe apart from Fitzcarraldo.

"The director was taking risks very few directors in the history of film have taken: being chased by an angry mob, armed to the teeth. When people are triggered in a crowd, certain things can happen they wouldn't do individually."

Baron Cohen recalled how he had a panic attack one morning as he stayed with two Donald Trump-supporting conspiracy theorists as he was concerned they would expose him.

"It was 6am and I started pacing around my room, thinking, how am I going to keep in character? They're going to see through me. It was bloody terrifying."

He added: "I've had threats since 'Ali G' and in my experience publicising them only does one thing: lead to more threats. We are in a very violent time. If you're protesting against racism, you're going to upset some racists."

In the candid interview, Cohen discussed his 2016 scripted comedy-action movie Grimsby failing at the box-office 

"Any flop is difficult. But in retrospect, the experience was fantastic. I was on the trajectory of a comedy movie star in Hollywood where you make a certain amount of movies that have to do well at the box office. The great thing about having a complete bomb was being liberated from that."
