Haggerty certainly looks the part, and his resemblance to Hamilton helped him land the job.
But what the producers didnt know yet was that Haggerty already had some experience playing Hamilton.
That was when I really learned about Hamilton for the first time, he says.

I got a hold of Ron Chernows book.
That changed everything for me.
Hes an unsung hero.
I picked my jaw up off the floor and said thank you.
[Seth] helped mold that scene and made it great, says Haggerty.
But heres somebody local who turned in an amazing audition.
And thats how Sean became Hamilton in the show.
His upcoming scenes at West Point with Hamilton are the first time hes appeared since.
To really show Washington, you oughta show him with his inner circle, says Haggerty.
I know that Ian was very pleased with having Hamilton being brought into the story.
On those days that we were shooting on set, it just seemed to make so much sense.
I mean, hesthere.
Its almost impossible to separate Hamilton from this story at this particular point.
So Im waiting for the call.
The moment they call me, the answer is yes.
In other words, Haggerty has no intention of throwing away his shot.
