Jesse Stone is a far cry from Thomas Magnum. With over five decades in the business, Tom Selleck stepped into another career-defining role as the titular character in the made-for-TV movie franchise Jesse Stone. The series is based on the characters of a 21-book crime novel series by Robert B. Parker. For over a decade, Selleck stepped into the shoes of a brooding, weathered police chief with a past of his own. Premiering primarily on CBS and rerunning on Hallmark Channel, these TV movies were a hit with audiences.
