Following a restful Labor Day weekend, Katie Holmes was once again spotted arriving at the Minetta Lane Theatre for another day of “All My Sons” rehearsals.

The “Dawson’s Creek” darling sported a baggy grey shirt along with a pair of what appeared to be her husband Tom Cruise’s jeans.

And it sounds like Katie will have more than the opening night jitters to worry about when she makes her big Broadway debut.  Reportedly, an Anti-Scientology activist group is planning to protest outside the Gerald Schoenfeld Theatre when the show officially opens on October 16th.

A group spokesperson told press, “We aren’t looking to shut the play down, we don’t have the power to do that; we just want to prove a point.  We want to draw attention to Scientology, and hopefully get Katie out of it before it’s too late.”
