A new trailer for an HBO documentary exploring the Boston Marathon bombing and its aftermath was released this week.
“Marathon: The Patriots Day Bombing,” is set to premiere on November 21, according to Boston.com.
The film explores the struggles of survivors, as well as first responders, members of the media and others who were affected by the 2013 attack.
Documentarians Ricki Stern and Annie Sundberg — who have writing, directing and producing credits on the film — also teamed up with reporters at the Boston Globe to create the film. The paper won a Pulitzer Prize for its coverage of the attacks.
