Directors Tracy Droz Tragos (pictured, left) and Rory Kennedy (right) have joined the roster at Nonfiction Unlimited, a production company that represents documentarians for commercial work.

Droz Tragos’ latest film is Rich Hill, a portrait of three boys from a poor rural town in Missouri that won the Grand Jury Prize for U.S. Documentary at the Sundance Film Festival earlier this year. The film just screened at Hot Docs and will begin rolling out theatrically in the U.S. on July 18.

Kennedy has produced and directed more than 35 docs, including Ethel, about her mother, and Last Days in Vietnam, which also premiered at Sundance in January. The latter film was produced for U.S. pubcaster PBS’s ‘American Experience’ series.

“I see commercial work as an extension of my filmmaking, capturing stories and real moments that hold an emotional truth and connect people,” said Droz Tragos in a statement. “Great advertising fosters meaningful bonds between brands and their customers and that’s the kind of work I’m looking forward to creating.”

Kennedy added: “Commercial directing is a really creative discipline with lots of possibilities and opportunities for a documentary filmmaker. I believe I have a lot to offer the commercial world given the breadth of my work so far.”

Nonfiction Unlimited also represents doc-makers Steve James, Barbara Kopple, Albert Maysles, David Gelb and Stacy Peralta.
