The offbeat documentary Rodents of Unusual Size, with its bizarre subject, is charmingly addictive. That subject is the nutria, a 20- to 30-pound Argentine rodent that threatens Louisiana’s wetlands and coastline. Yes, 30-pound swamp rats with orange teeth.
Although Rodents of Unusual Size is decidedly non-preachy, the nutria is serious business. Imported for the commercial potential of its fur by a Tabasco sauce heir, nutria escaped into the Louisiana wilds and propagated wildly. When the US fur market crashed in the 1990s, the locals stopped trapping them, and Louisiana’s nutria population exploded to 20 million.
The problem is that nutria eat the roots of the vegetation in the Louisiana wetlands, causing erosion that has converted at least 42 square miles of land into open water. Worse, those wetlands are the storm buffer for the rest of the state.
Louisiana offers hunters a $5 bounty for the tail of each dead nutria, which has reduced the nutria population to a more manageable 5 million. We even meet a guy whose official job title is Nutria Tail Assessor.
One of the reasons I love Louisiana is that folks just don’t take themselves too seriously there. Even when they are focused on the grave environmental impacts of the nutria invasion, they still appreciate the absurdity of a 30-pound, orange-toothed swamp rat. (And, fittingly, Rodents of Unusual Size is narrated by Louisiana native Wendell Pierce.)
Along the way, we are also introduced to nutria fur and the fur company Righteous Fur, nutria meat, nutria sports mascots and even nutria as pets.
But most compellingly, we meet Thomas Gonzalez, an 80-year-old bayou native, nutria hunter and bon vivant. Gonzalez is a force of nature, complete with strong-willed opinions and some impressive dance moves. Gonzalez serves as the voice of Louisiana and finishes the movie with a profound perspective on the nutria.
I saw Rodents of Unusual Size at Silicon Valley’s Cinema Club with filmmaker Chris Metzler available for Q&A. Metzler and his colleagues Jeff Springer and Quinn Costello filmed Rodents of Unusual Size over four years during Louisiana’s nutria season (November to April). The affable Metzler is a font of nutria knowledge, full of tidbits like albino nutria being prized by taxidermists. Because nutria are very difficult to spot and film in the wild, the filmmakers used Nooty the stunt nutria throughout the film. Nooty joined the filmmakers in creeping along the red carpet at various film festivals and has her own Facebook page.
Thomas Gonzalez alone is worth meeting on film, and, as told by Rodents of Unusual Size, the story of the nutria is quirkily fascinating. This weekend, Rodents of Unusual Size will be opening a new run at theaters in Marin and the East Bay.
