Re: Could I become a Niner? hmmm....
When those first few early scripts were being written, the roles hadn't even been cast yet. The only one the writers really had a lock on from the beginning was Colm Meaney's O'Brien. Once the rest of the cast was assembled, writers and actors gradually found their voices. It happens a lot with any series that isn't put together for a specific star.
Moe: I'll take the blonde!
Larry: I'll take the brunette!
Curly: I'll take the Black and Tan!
