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.

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 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.

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 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 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.
