True crime is still all the rage between podcasts, docuseries, and dramatizations and Hulu is putting the spotlight on the Boston Strangler in March. Keira Knightley stars as reporter Loretta McLaughlin, who became the first person to piece together the fact that a serial killer was stalking 1960s Boston and murdering women. Working with her friend and colleague Jean Cole (Carrie Coon), the pair pursue the truth despite pushback from the patriarchal police and news organizations and the fact that they may be making themselves targets of the killer himself. Chris Cooper, Alessandro Nivola, David Dastmalchian, Rory Cochrane, Robert John Burke, and Morgan Spector co-star, and the movie was written and directed by Matt Ruskin, who previously produced The Infiltrator and directed Booster and Crown Heights. Boston Strangler is out on March 17th and you can check out the trailer below.
