The Rock, aka Dwayne Johnson, took to Instagram Thursday to announce his latest project with HBO. Johnson is currenlty shooting Ballers with the same channel, and his reality show Wake Up Call  just wrapped up its first season on TNT.

This project touches close to home for The Rock, who says: “’ROCK & A HARD PLACE. We’ve officially started production on our next documentary film project with @HBO. From armed robbery to attempted murder, we’re taking you inside one of the most unique and successful boot camp prisons in the world. They break these young offenders down in a hard core way, only to build them back up to make them better men and women once they’re released. We partnered up with the producers of LOCK UP and HBO’s best documentary filmmakers to bring you a passion project of ours. With my multiple arrests, I was once one of these kids. One poor f*cked up decision after another. I turned my life around, and hopefully along the way we’ll help a few turn theirs around too. Production starts now. #HBODocumentaryFilms #7BucksProductions #44BlueProductions #DadeCountyFlorida #RockAndAHardPlace”
