I'm kind of happy to know there may be some kid or teenager now who might never have had the chance to see my Broadway performance, but gets a taste for what it might have been like now, because they can see Clint Eastwood's film."

It was a surprise to me and a happy accident that it was such a skill [natural falsetto] - a latent skill and that there was a way to exploit it. And it was a key to playing great role Frankie Valli in such a huge show.

But when you get to know a character so well, you start to have insights that you can't show because you're confined to your script of your hit show.

I think Frankie Valli did everything right. He kept singing. And you also have to remember, he was confined to a certain society, which was this sort of like - the wrong side of the law kind of society of Italian guys from the streets of Belleville, New Jersey. So he found his way.

I definitely worked really hard to evoke Frankie Valli, but not do a strict imitation, because I feel that a strict imitation is not as compelling to watch.

It's funny - Frankie Valli's story and that advice that he was just getting from, you know, Christopher Walken's character, is very true for someone who's in a creative field.
