Martin-Smith entered the entertainment industry in the early 1980s working as a casting agent from offices in Manchester's Royal Exchange. From there, he challenged the "London-centric" attitude of many in the business, championing the cause of local talent and establishing many actors in film and television. His first success in the music industry was the artist Damian who had a UK top 10 hit with a cover of "The Time Warp" in 1989. He also ran the Film Artist Agency at Half Moon Chambers in Manchester.
