Paul McCrane (on his thoughts on how ER has changed): I was still on the show when most of the current cast had at least joined — like Maura Tierney, Mekhi Phifer but there are a couple of new faces. It's sort of 'ER: The Next Generation' right now, and I think that was a conscious decision made on the part of the producers. The format of the show is such that it allows for that. As long as they keep introducing and writing interesting new characters, it gives them new vantage points from which to tell these inherently dramatic stories. In some franchises, it's silly when they try to revolve the door a little bit, but with ER it makes sense. It's an interesting confluence of personal and dramatic stories in the life and death atmosphere of the ER.
