I approach the singing kind of like with dialect thoughts in my mind. I have to sound like this on certain things to give that Frankie Valli flavor.

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.

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.

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.

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

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.

I don't have a Jersey dialect. So when I approached the singing, I approached it the same way as an actor I approach a dialect, just as a singer.
