I think you couldn't do this role or you couldn't be Frankie Valli himself unless you had a natural falsetto. And I had sort of discovered it by accident as a child or a young adult when you realize you have a special skill that you don't really have any use for you, and you just take it out at parties or to amuse your friends or to annoy your girlfriends.

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 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.

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 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 know, for me, you know, my generation - I never would have known anything about Robert Preston's performance in 'The Music Man' if there hadn't been a film where he played the part. I just heard how great he was on Broadway way before my time.

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.
