"One of the most disturbing problems in our world today is human trafficking, and particularly the trafficking of children," Gibson says in a short promo for the film.

"Our future is our children. Now the first step in eradicating this crime is awareness. Go see Sound of Freedom."

The Braveheart director's words add to the anticipation for the upcoming movie, debuting on July 4, featuring acclaimed actor Jim Caviezel, who also portrayed Jesus in Gibson's powerful film The Passion of the Christ.

Caviezel recently revealed traffickers are making billions of dollars in the global child sex trade, especially with the collapsed U.S. southern border and in embattled regions like Ukraine.

He also appeared on Steve Bannon's "War Room" program earlier this month to expose the disturbing child trafficking networks exploiting kids worldwide, claiming sources have informed him of a lucrative trafficking scheme used by globalists to get high off human adrenochrome.
