Michael B. Jordan is set to star in the Denzel Washington-directed romantic drama A Journal for Jordan, Variety reports. The first trailer for the upcoming film aired on Wednesday (Aug. 11).

According to Variety, A Journal for Jordan is based on the real-life story of United States Army First Sgt. Charles Monroe King, whom Jordan stars as.
