In this exclusive clip from new Irish film 'The Guarantee' actor David Murray plays the late Minister for Finance Brian Lenihan as he addresses the media prior to the infamous night of the bank guarantee.

'The Guarantee' covers the events leading up to, and of that night, when the Irish government decided to guarantee the entire domestic banking system.

The decision, which was taken by a handful of men in a room in the middle of the night, had long reaching consequences - in another 30 years or so it will have cost over €60 billion, the most expensive bank rescue in history.

The film kicks off four years before that night and charts the peak of the boom and the beginning of the bust.

The exclusive clip shows a reporter asking Lenihan, "Is the government about to back an Anglo rescue of Nationwide?" to which he replies, "Nationwide has rallied. Nobody is talking about a rescue."

The reporter continues, "Have you talked about it? Have you discussed this with Anglo?"

Lenihan replies, "No."

"Really minister?"

"No."

The reporter says, "Because it would be like tying two stones together. They would both sink."

Lenihan replies, "It's not something we are considering."

Joining Murray in the cast are Gary Lydon as then Taoiseach Brian Cowen, Peter Coonan as David Drumm, Morgan C Jones as Sean Fitzpatrick, and Orla Fitzgerald as hedge fund manager Kate Walsh.

Speaking to the Sunday Independent recently director Ian Power said, "The characters are tragically heroic in their own way. They are in a desperate situation because of their own actions and also events outside their control.

"We did not embellish or tabloidise the story. We told it as straight as we can. We didn't have to mess with it. Every element of the story is so controversial. The power of truth has enough impact."

Based on Colin Murphy's stage play Guaranteed! the movie is produced by John Kelleher Media in association with the BAI, the Irish Film Board and TV3.

The Guarantee hits Irish cinemas on October 30.
