Oscar winning actor Denzel Washington returns to the director’s chair for drama “A Journal for Jordan”, a story about love and life lessons based on a memoir by Pulitzer Prize winner Dana Canedy.

Starring “Black Panther” actor Michael B. Jordan and “Monsters and Men” actress Chante Adams, the movie tells the story of how after Canedy’s fiancé US Army First Sergeant Charles King was killed during the Iraq war, she turned a journal he left for their son into an essay and later a book.

The film depicts the teachings King wrote to the then infant Jordan and the couple’s love story.

“I read (the script) and I went ‘Whoa ... Oh, we got something here, I’ll direct this’,” Washington told Reuters in an interview.

Jordan, also a producer on the film, said its message was simple: “I want people to take away from this movie that ... through love anything’s possible.”

King began writing the journal in 2005. Former journalist Canedy, who was part of a New York Times team that won the 2001 Pulitzer Prize for a series on race relations in the United States, published her memoir in 2008.

She said King would be moved by the film.

“He would be humbled. He would be bashful about it and he would be incredibly proud,” said Canedy, currently senior vice president and publisher at Simon & Schuster.

“A Journal for Jordan” will be released in US cinemas on December 25.
