After her performance – which Cruise's mother, Mary Lee Mapother, declared, "Fantastic!" – Holmes chatted with PEOPLE: PEOPLE:
The show has been in previews for weeks. Did it feel different onstage tonight?
There was definitely a lot more energy. The whole cast, we all got there about an hour and a half [early] and we had gifts for each other and we were running up and down the steps .... It felt like Christmas.
Is Tom supportive?
He comes [to the theater] a lot. He came to the dress rehearsal. I was so nervous, and I saw him out there, and he made me feel so much better. Every time he's there, I just feel like it's going to be okay.
Is it difficult balancing your theater work with being a mom?
It's a great schedule, because [Suri and I] get to spend the whole day together and then I go and do the play. Then I come home and we play some more!
And Suri had her own dressing room at the theater?
Yeah, we have a dressing room that is transformed into a playroom. It has a little piano.
First motherhood, then a marathon
, and now your Broadway debut. What's your next big challenge?
