This July 23 will mark the 50th anniversary of the Detroit Riots, which were among the bloodiest in the history of the United States.

Academy Award Director Kathryn Bigelow has a movie coming out called 'Detroit' and the trailer indicates its plot will revolve around the darkest incident of the rioting.

The movie is due out in August, and it appears to revolve around the darkest incident of the rioting, an event that has come to be known as 'The Algiers Hotel Incident.'

As the height of the rioting, police were called to a dingy hotel off Woodward Avenue frequented by vagrant men and prostitutes. National Guardsmen outside the hotel heard shots fired from inside and feared a sniper was shooting from the roof.

When the police and Guardsmen stormed the building, they killed two suspects and later killed a third during interrogations. The incident was the subject of several books, most notably John Hersey's 'The Algiers Hotel Incident'.

Bigelow won the Oscar for the movie 'The Hurt Locker' starring Jeremy Renner.
