Movie star Jon Voight wants Americans on high alert because he fears another 9/11 terrorist attack is near. The Deliverance star admits he's more than a little nervous about ongoing immigration issues, and fears Americans have become complacent as the sixth anniversary of Al Qaeda's attacks on Washington, D.C. and New York approaches.

He tells RadarOnline.com, "I certainly hope we're paying close attention to all those people crossing our borders who might be dangerous to us. We know for sure there are cells in the United States that are ready to erupt. We know that (Lebanese paramilitary organization) Hezbollah is here; we know there are cells from different terrorist organizations that are here and operational and that there are others waiting too.

"So, listen, it's a serious business. It's wartime, guys. Because we don't have a continuous attack on our shores, we can get complacent. We've got to all be alert now."
