Katie Holmes set out for yet another trek to rehearsal for All My Sons in NYC yesterday. Not as much fun as seeing Suri clean up at the Build-A-Bear workshop, but the good news is that Katie's been getting more praise from costars. John Lithgow couldn't help gushing about her performance, saying, "Katie is lovely in the play, and she's been such a sweetheart to work with. She has worked so hard — this is a tough, tough play. Katie is acting with thoroughbreds and she's doing a wonderful job! She's had to really push herself." He went on to call the whole Cruise family "adorable," and while we can't argue on that one, we're still curious to read what all the critics have to say, too.
