I remember him as the sadistic Major in the NBC show Revolution, about a world where the electricity stopped working.
He also played the Mirror on the Wall/Sidney the reporter in the first season of the ABC show Once Upon A Time.

Ahh, now I remember Revolution. Didn’t much care for it, but Esposito was definitely more than competent in that role. Overall, though, I thought the series was overwrought. I really didn’t care for the lead actor or his family. Not much on the broadcast networks is worth watching. I sort of like 9 1 1, Good Doctor, Big Bang Theory and Young Sheldon. And Gotham. Not much beyond that. Need to cut the cord. Spent some time checking out the streaming available but haven’t found anything that really grabs me yet.
