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.

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've learned to keep my work on the stage or on the screen.

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

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.

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.
