A large film crew based out of Los Angeles has made Granby its home this week, conducting interviews and setting up establishing shots in preparation for a new, feature-length documentary about Marvin Heemeyer and his infamous June 2004 rampage.

The untitled documentary is currently in its infancy as production crews begin conducting on-camera interviews with key players from the 2004 event in which Heemeyer destroyed numerous buildings around Granby while driving an armor-plated bulldozer, ultimately taking his own life before he could be apprehended by authorities.

The documentary is attempting to set itself apart as an in-depth, professional documentary focusing on Heemeyer’s life, with his friends, family and those most affected by the incident share their stories.

Patrick Brower, former Sky-Hi News editor and publisher and author of the recent “Killdozer” book that chronicles the incident, offered his lengthy, detailed recap of the event, on which he reported extensively, and the events leading up to the rampage. Brower spent hours in front of the camera this week telling his story, sitting in his former office at Sky-Hi News.

Others interviewed around the county, who were too familiar with the June 2004 incident, included local law enforcement, business owners, Heemeyer’s friends and more.

Producers of the documentary hope to shop around the film as it wraps production, namely hitting the major film festivals to nail down a distributor. The documentary will feature a full runtime, which could near 120 minutes.

The film crew, which has been seen around Granby over the last several days, is scheduled to leave Colorado next week with plans to return to wrap filming sometime early this summer.

No details on the film’s release date have been established.
