The show is based on the memoir A Higher Loyalty by former FBI director James Comedy, who is played by Jeff Daniels.

Ray’s story follows the 2016 election as well as the early days of Trump’s presidency, until Comey was sacked in May 2017

The new trailer provides our first chance to listen to Trump’s vocal impersonation of the president as he talks about how people in the FBI “have it in for me”.

He later states, in true Trump style: "Nobody gets treated as unfairly as I do. I need loyalty."

The impressive cast of the show also includes Jennifer Ehle as Patrice Comey, Holly Hunter as former Deputy Attorney General Sally Yates and Kingsley Ben-Adir as Barack Obama.

Ray told Vanity Fair that Gleeson initially turned down the lead role and that many other actors followed suit, before the Irishman finally agreed.

In depicting Trump’s recognisable appearance, Ray revealed that the make-up and costume team actually “dialed down” elements of the president.

He added: “We made the contrast between the bags under his eyes and the orange skin softer than it actually is.

“We made the hair a little less cartoonish than it actually is. We made the suits fit a little bit better.

“We went out of our way to play fair because we felt we owed that to the public.”

It has been made clear throughout the process of making The Comey Rule that this is a serious portrayal of the president, vastly different to Alec Baldwin’s Emmy-winning performances on Saturday Night Live.

The Comey Rule will air over two nights on 27-28 September, with a UK release yet to be confirmed.
