The original character choices
Could you imagine if the cast had been made up of different actors?
Kauffman and her writing partner, David Crane, initially had a different vision for Monica.

“We had Janeane Garofalo’s voice in our head.
And what of the other actors?

And that also jived with what some of the cast was thinking.

The live audience is such an integral part of the show.”
