Mr. Derek Haas isn't, however, writing the screenplay to the film adaptation to his novel. That job goes to Mr. Frank Baldwin.
Here is a statement from deadline.com about The Silver Bear and Michael B. Jordan:
Nickel City optioned the rights to the book franchise last year and hired Baldwin, who also scripted the Liam Neeson-starrer Hard Powder.
Said Nickel City’s Rungta: “We could not be more excited to work with Michael and Lionsgate. We have been huge fans of Michael all the way back to his days in The Wire, and from our first meeting we knew that he was the perfect fit for the role of Columbus.”
In confirming the story exclusively for Deadline, Lionsgate Motion Picture Group chairman Joe Drake called The Silver Bear “the kind of story that needs to be experienced on the big screen and Michael is the perfect movie star to inhabit the skin of this dynamic character and take us into the cinematic world of Columbus.”
