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.

I was a Hollywood musical fan as a kid, and I know how rare it is for someone who originates the Broadway role to get to then do it on screen.

It was great to play for a live audience on a stage.

When you look at sort of pop stardom now, some of these singers, it seems like the idea of them was created in a marketing meeting, and then they just found someone to sort of fulfill that role.

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.

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."

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.
