American singer, actress, director and producer Barbara Streisand has joined The Promise film to #KeepThePromise to never forget.

“We are all children of immigrants. I’m Barbara Streisand I vow to keep the promise to never forget,” she says in a video shared on Facebook.

Set in 1914 right before the fall of the Ottoman Empire, the film follows Michael Boghosian (Oscar Isaac), a hopeful medical student who arrives in Constantinople to bring modern medicine to his ancestral village of Siroun in Southern Turkey. In the bustling capital, he soon meets Chris Myers (Christian Bale), an American photo-journalist, and Ana (Charlotte Le Bon), an Armenian artist. Both Michael and Chris soon fall in love with Ana and a love triangle ensues just as the Turks join the war on the German side, turning against the Armenians. Everyone must find a way to settle their differences in order to survive the coming chaos.
