They're hereee....

Katie Holmes will make her Broadway debut soon, and word on the net is that her performance "will be attended by an anti-Scientology group wearing masks." What a visual.

A "rep" for the group said, "We aren't looking to shut 'All My Sons' down, we don't have the power to do that, we just want to prove a point."

"We just want to save Katie. We want to draw attention to Scientology, and hopefully get Katie out of it before it's too late."

The clan says they're a "leaderless worldwide group of concerned citizens." They allege the "dangerous cult of Scientology has a well-earned reputation for harassing critics and openly critical ex-Scientologists at their homes and workplaces."
