How a head became a regular character

A character called Morn, who was really just a background character, one of the original nine heads that we designed for Deep Space 9, and when he walked in, the Director looked at him and said, 'I want that one, put him at the bar.' And he sat at the bar for the next seven years.

We called him Morn almost like Norm on Cheers, who's sitting at the bar the whole time. The same man played for the entire seven years. It was nice. And the funny part was the scripts would come out and there would be lines for him, and then, by the time we got down to shooting, the lines were gone, so he never spoke in the seven years.
