You can’t blame Matt Wilson if he’s hearing voices these days.

As J. Pierrepont Finch, the lead character in “How to Succeed in Business Without Really Trying” – which begins a three-week run tonight at the White Plains Performing Arts Center – Wilson hears the “voice” of the book offering tips on how to achieve what the title suggests.

The voice is provided by Tony Award winner David Hyde Pierce (“Curtains”).

In the musical – which won six Tonys, including best musical, and the Pulitzer Prize in 1962 – Finch, a window washer who dreams of climbing the corporate ladder, begins doing just that, when he follows the book’s advice.

But there are other voices, too.

There’s J.B. Biggley, the big boss of World Wide Wickets, a pompous and impervious character played by Nick Wyman, a Broadway veteran of “Les Miserables” and “The Phantom of the Opera.”

“He’s risen to the top with the force of his personality,” Wyman says. “I play arrogant blowhards a lot.”

In September, Wyman brings “A Tale of Two Cities” to Broadway, playing the opportunistic Barsad, at the Hirschfeld Theater, where Hyde Pierce is now appearing in “Curtains.”

Wyman, a longtime Westchester resident who now calls Yonkers home, says he’s enjoying the short 20-minute commute to the theater in downtown White Plains.

Wilson is a fixture on the Emmy-winning PBS kids series “Cyberchase.” He plays Harry, the juggling unicyclist who finds math all around him.

The part of Finch proved difficult to cast, director Eleanor Reissa says.

“All we needed was a guy who sang great, acted great, was funny, personable, warm and could dance. That was all we needed,” she says. “Matt came in and won the part hands down.

“There were maybe three other guys before Matt and it was a nail-biter – ‘Where is the lead?’ – and then the lead walked in,” the director says.

“You have to love Finch,” she says. “And Matt walked in and we all loved him.”

“Say that again,” Wilson begs.

Finch also hears the voices of back-stabbing co-workers who want to climb that same corporate ladder. His chief rival, Bud Frump, is played by Ron DeStefano.

And in one crucial scene, he’ll listen to his own comforting voice in the song “I Believe in You.”

Of course, the fact that the pep talk is sung in a men’s restroom provides a bit of irony.

Wilson knows there’s a lot riding on that song.

“It’s such a visible moment and everyone knows that song and I want to do it the justice it deserves, but make sure it’s still part of the show and part of the story.”

“How to Succeed,” with music and lyrics by Frank Loesser and a book by Abe Burrows, Jack Weinstock and Willie Gilbert, is produced by Jack W. Batman, who turned an underused auditorium next to a multiplex into a professional home for classic Broadway musicals. He’s already lined up next year’s slate of musicals.

Reissa was a 1991 Tony nominee for her direction of “Those Were the Days.” She says this cast of 22 was chosen for its comic timing.

“That’s a big key to this show,” she says. “This cast has timing and a great sense of humor – and they can do comedy with a capital ‘C.’”

Wyman agrees. “It’s a style that’s maybe gone out of style. It’s a style that unapologetically has its elbow in your ribs. It’s setup, setup, punch line. It makes no bones about it. If you’re a comic actor, it’s billboard-sized fun. It’s laughable it’s so bold.

“That’s another thing about this show – and Eleanor’s great about making sure that we don’t do this,” Wyman adds. “You can’t smooth off the edges and make it naturalistic and sort of kitchen sinky. People have very clear-cut ambitions and goals and motivations and things they’re going for. It’s very sharp and clear and bold and bright, with all these ‘60s bright colors.”

“These are not people in quotes,” Reissa says. “There’s not a comment on Biggley. Biggley is Biggley. He does what he has to do without us going, ‘He doesn’t mean it’ or ‘He’s kidding.’”

“They’re real people acting in very bold ways,” Wyman says, to finish the thought.

Into this mix comes Finch, the window washer who is open to anything, without being too calculating, Wilson says.

“He’s making sure that things go his way but he doesn’t necessarily know it’s going to go his way until it goes his way,” he adds.

“Sometimes there’s a plan, sometimes there’s not, but he takes advantage of both situations.”

What can we learn from Finch?

“You need to look for opportunities, take advantage of opportunities that present themselves to you, but also to make opportunities for yourself,” Wilson says. “It’s OK to be invested in self, but also to be aware and concerned of others.”

Reissa smiles.

“To me, that’s a very Finchian response,” she says. “Sometimes I say to Matt, ‘OK, you have to snow this guy,’ and he says, ‘OK! Absolutely!’ And I say, ‘Are you snowing me? Is this you snowing me now?’

“It’s hard to tell sometimes, because he’s so charming and lovely and personable, that when he says ‘Yes! Absolutely! I get it!’ I really wonder if he just wants me to be quiet.”

The man who’ll sing “I Believe in You” appreciates that bit of self-affirmation. And he might just be thinking about another voice – a voice from his past.

“James Earl Jones spoke at my graduation. I went to Vassar,” Wilson says. “And one of the things he said was ‘There’s no one else that will tell you ‘Good job! You can do that!’ When it comes down to it, it’s going to be you. Your mom’s not necessarily going to be there. Or your wife, or whoever. You’re the only person who can say ‘You’re going to do this’ or ‘You can do this.’”

Then, as if to prove Reissa’s point about comic timing, he pauses before adding: “And then he said ‘May the force be with you.’”
