Another Olmstead production gave Pellegrino a bunch of work in the late '90s/early '00s.

"I was one of only a couple of actors that worked on that show three or four times, doing different characters. We developed a relationship from that, and then I did this weird little pilot called NYPD Blue 2069," he says.

And now, "he puts me in whatever show he's doing, which I'm grateful for."

I love this show. I miss it so much. Ticks me off that all of the seasons aren't on DVD yet; especially the last two. I was addicted back then.
