Katie_holmes_tom_cruise_suri_cruiseThe last play Katie Holmes appeared in was back in high school in Toledo, Ohio.

But that’s not stopping Tom Cruise’s wife from prepping for hew new role in Arthur Miller’s "All My Sons" on Broadway this fall.

From Toledo to Broadway? Gulp.

Naturally, some seasoned stage actors at the Tony Awards last night had some words of advice for Katie Holmes via People.

"She’s a pro and I’d say to be herself," says John Lithgow, who will costar with Holmes in the Miller play.

"She’s going to be wonderful. I’m looking forward to working with her. We haven’t worked together yet, but it’s going to be great."

Brooke Shields, who was Roxie Hart in "Chicago" in 2005, said of that leap from screen to stage: "She will be so happy about making that decision. There is nothing like it. It’s the Olympics. It’s the college of theater."

And Tony Award-winning actress Kristin Chenoweth says Holmes should focus on getting her Zs.

"I would recommend her just to stay [healthy] and get a lot of good sleep and drink lots of water," Chenoweth says. "It takes so much energy to be on stage 7 days a week so she needs a good night’s sleep everyday. But I’m sure she will do just fine."

Got any words of advice for Katie about doing Broadway? Or about anything? Maybe about letting her daughter, Suri, hang on to her baby bottle? Now’s your chance to vent!
