Michael Bay is getting a bit more serious for his next movie, as rather than transforming robots, he’s heading for the very real and deadly events that took place at the US Mission in Benghazi in 2012.

Now he’s starting to put together his cast, as Variety reports that John Krasinski is the first to sign up, with the former Office actor set to play a Navy SEAL in the movie.

The movie is based on Mitchell Zuckoff’s book, which centres on six members of a security team. After the facility came under attack from militants angered about the recently release of a trailer for an Islam-bashing film called ‘Innocence Of Muslims’ and the anniversary of 9/11.

The team fought to defend the lives of the Americans in the compound, although the attack claimed the life of US Ambassador Christopher J. Stevens and a foreign service worker, while two contract workers died in a second attack at a nearby CIA facility.

Chuck Hogan (The Town, The Strain) wrote the screenplay.

It’s certainly something different for Bay, who’s better known for hyperbolic action and explosions in movies where the plot is more than a little ridiculous. Here though he’s dealing with real and very controversial events, and it’s sure many will be watching closely to see how he handles it.
