PHILADELPHIA (CBS) – Some big names in Hollywood are joining the activists speaking out against the National Security Agency’s domestic surveillance program. There’s a rally this weekend in Washington, DC.

“Every american is at risk of getting caught up in the NSA dragnet,” says Oliver Stone in the YouTube video.

“The tools for surveillance have never been more powerful, and the threat to our civil liberties has never been greater,” says John Cusack.

“We need to end mass, suspicionless surveillance,” Maggie Gyllenhaal says.

The director and actors appear in the PSA from the Electronic Frontier Foundation, calling on Americans to get angry about the NSA’s data grab.

Pentagon Papers whistleblower Daniel Ellsberg is there, too.

“We’ve seen this story before, and we decided it was wrong.”

The EFF says more than half a million people have signed its online petition to Congress at The group wants people (including a Philadelphia contingent) to come to Washington’s Union Station for a rally against mass surveillance — at noon on Saturday, the 12th anniversary of the signing of the Patriot Act.
