Robin Wright Emmys - P 2015

The celebrity-backed campaign is led by the United Nation's International Labour Organization and aims to help the 21 million men, women and children who are in forced labor.

With 21 million people (according to the International Labour Organization) caught in modern slavery across the globe, Hollywood is lending a voice to the cause.

Robin Wright (House of Cards), David Oyelowo (Selma, Nightingale) and Wagner Moura (Narcos) are some of the many celebrities participating in PSA videos bringing awareness to human trafficking as part of the 50 for Freedom campaign, which launched on Tuesday. Wright, Oyelowo and Moura give voice to powerful testimonials of men, women and children from around the world who currently are forced to work in factories and even prostitution with little to no pay.

In the three released videos, Wright tells the story of a young woman who was tricked into prostitution, while Oyelowo voices the story of a man working in agriculture who was denied pay. Both victims were beaten severely when they made attempts to leave.

The campaign effort, led by the International Labour Organization, sheds light on the $150 billion made in illegal profits, according to the 50 for Freedom website. The ILO hopes to have 50 countries endorse its Protocol on Forced Labour — a treaty that will allow governments to prevent forced labor (Niger already has ratified the protocol).

"It is unacceptable in our modern society that people are working in degrading conditions and are enslaved," said ILO Goodwill Ambassador Moura. "Slavery exists today all over the world, and we need to shine a bright light on it and expose it for what it is. Join me in supporting the ILO's 50 for Freedom campaign today."

Wright, Oyelowo and Moura aren't the only celebrities lending their voices to the cause. More celebrities, including Tim Roth, will be releasing future video clips via social media.
