The Office star plays one of the six heroes in new movie 13 Hours: The Secret Soldiers of Benghazi, which tells how the men, who were by then working as CIA security contractors, fought to protect the American Ambassador and his staff during the 2012 terror attack.

Krasinski admits he knew nothing of the story before signing up for the film because many reports at the time played down the terrorism angle and described the incident as a 'protest'.

However, the actor is glad U.S. citizens can finally see a true representation of what happened during the siege as the six men deserve recognition for their bravery.

Krasinski tells U.K. TV show Good Morning Britain, "It is such an important story to acknowledge these six guys and what they did. There's a huge political storm around it. I think a lot of people have heard the word Benghazi, I certainly thought I knew everything there is to know about it - I watch the news and I read the newspaper - and I was embarrassed to realise I had never heard the story of these six guys... To me it's the true definition of heroism. I think in a world of superhero movies, it's nice to tell a story about real heroes."
