In 1993's third instalment of "Prime Suspect", Miller played a young man victimized as a child by a paedophile. His first notable acting role that year was in the soap opera "EastEnders" wherein he played Jonathan Hewitt. Miller later revealed he had been offered a contract to remain on the show but declined: "It was five weeks' work and I made more money there than I ever had in my life. Then they offered me a year's contract. I said no, thank God. I thought I should get out of there while I still could."
