Oscar Isaac is observing Human Rights Day.

For the occasion, observed Dec. 10, the actor recorded a PSA urging viewers to “please support the organizations that work tirelessly to protect and promote our human rights.”

The actor’s video message follows his starring turn in the 2016 movie The Promise, which tells the story of the Ottoman Empire’s Armenian genocide at the end of World War I. Since the movie’s release, a slew of celebrities have pledged to “keep the promise” to help displaced refugees and fight for human rights.

The late rocker Chris Cornell — whose family continues to carry on his work with refugees — wrote a song for the movie; the track, also titled “The Promise,” earned Cornell a posthumous Grammy nomination in the best rock performance category.
