Diamond Men is a 2000 film, a crime drama starring Robert Forster and Donnie Wahlberg.^[1]

The independent film was written and directed by Dan Cohen, and was screened at the Hamptons International Film Festival in October 2000. It was released to select theatres in the US on September 14, 2001.

Eddie Miller (Robert Forster) is a traveling salesman, servicing towns in Pennsylvania. He sells diamonds and jewelry to 'Mom & Pop' one of a kind stores. In the business for thirty years, he is weary of the grind after recovering from a heart attack, the recent death of his wife, and the corporate take-over that he senses will eliminate his employment. He is a 'liability', a dinosaur. A last task: train his replacement, Bobby Walker (Donnie Wahlberg). This is a 'road' film, 'buddy' film, and 'coming-of-age' film as the plot unfolds. Eddie eases up on the brash, uncouth Bobby, and they eventually develop a mutual respect; learning from each other. Tina (Jasmine Guy), a Madam with a heart of gold, and Katie (Bess Armstrong) as a reluctant prostitute complete the cast of characters.
