Katie Holmes kept right on her routine of rehearsing for All My Sons in NYC yesterday and today, and now she's less than a week away from the previewing the show starting on Sept. 18. We already know that Joshua Jackson plans on supporting his former costar [1], and she'll also get some love from her friend Jada Pinkett Smith, who said [2], "I am going to be there on opening night. I know she is going to be fabulous." Katie's fellow celebs won't be the only ones filling the seats — the show is slated to be one of the biggest non-musicals at the box office [3], despite recent rumors that sales were lackluster [4].
