Mark Greaney's on a roll. His new book, "Armoured," is out and so is the first Gray Man movie.As the author of more than 20 books, three of them collaborations with Tom Clancy before the author's death in 2013, Greaney is enjoying unqualified success.But his Gray Man character took his time before making a movie debut. "The movie rights were actually secured when I wrote the first Gray Man novel (he's working on his 11th now) in 2009," he told Steve Tarter.Brad Pitt was initially set to play the part and a script was written but that didn't happen. Things looked up when the Russo brothers, producers of "Avengers" and "Captain America" blockbusters, came on board to tackle the project.Netflix will stream the Gray Man movie starting July 22.Greaney used to write at the Starbucks in his native Memphis but had to give that up, he said, because too many folks were asking him to consider writing proposals of their own.For "Armoured," a story about high-powered mercenaries in Mexico, Greaney said he spent time living and training with real-life members of private armed forces to gain insight for the book.
