Wait, Rob Zombie grew up in Haverhill, but he’s making a movie about one of the Bruins’ rivals? Yes. Word is the rocker is at work on a film about the Philadelphia Flyers’ famed Broad Street Bullies. (The Bullies won the Stanley Cup in 1974 and 1975.) According to NHL.com, Zombie toured the team’s archives earlier this month, and hopes to have a finished script shortly. “It’s the greatest sports story ever not told, I guess,” said Zombie, who plans to film in Philly. “It’s been told other ways but not in film. Had to do it. It reads like fiction, it’s so incredible.” The story was previously told in the documentary “Broad Street Bullies,” which aired on HBO in 2010 and featured former players Bernie Parent, Bobby Clarke, Dave “The Hammer” Schultz, Bill Clement, and owner Ed Snider. Zombie described his movie this way: “It’s sort of like ‘Boogie Nights’ meets ‘Rocky,’ ” he said. “Because I know from the five-minute conversations I’ve had, that there’s a lot of good stuff besides hockey going on. It’s the characters.” No doubt someone could make a similar movie about the Bruins.
