Today brings our first look at Keira Knightley and Carrie Coon in Boston Strangler, a movie about the reporter who broke the story of the notorious serial killer.

In the film directed by Matt Ruskin, Knightley is portraying Loretta McLaughlin, the first reporter to draw a connection between a spate of murders in the Boston, MA area in the early 1960s. Coon is co-starring as Jean Cole, her co-worker at the Record-American newspaper who assisted her in investigating the case.

McLaughlin and Cole's pioneering reporting was all the more impressive given the overwhelming sexism they faced in newsrooms during the early 1960s. Ruskin told Empire: "I always loved journalism stories and in researching the case, I discovered these two journalists, starting with Loretta McLaughlin, the first journalist to connect the murders, and in her reporting, she actually gave the Boston Strangler his name.

"It was a really monumental story for her in her career in the early 1960s," he added. "She was a very ambitious reporter in a male-dominated field and this was a real turning point for her."
