Emily Kunstler and Sarah Kunstler (producers/directors) run Off Center Media (www.off-center.com), a production company that produces documentaries exposing injustice in the criminal justice system.

The sisters founded Off Center Media in 2000, and have produced, directed, and edited a number of short documentaries, including Tulia, Texas: Scenes from the Drug War (2002), which won Best Documentary Short at the Woodstock Film Festival, and was instrumental in winning exoneration for 46 wrongfully convicted people; and Getting Through to the President (2004), which has aired on the Sundance Channel, Current TV, and Channel Thirteen/WNET.
Other notable Off Center Media projects include A Pattern of Exclusion: The Trial of Thomas Miller-El (2002), a documentary about racism at the trial of Miller-El, who had been on death row in Texas since 1985; The Norfolk Four: A Miscarriage of Justice (2006), about four young men in Norfolk, Virginia, who falsely confessed to a rape-murder that they did not commit; and Executing the Insane: The Case of Scott Panetti (2007). These films have contributed to campaigns to stay executions and convince decision makers to reopen cases. William Kunstler: Disturbing the Universe is the sisters' first documentary feature.
