In 1958, while serving as the art director for a Greek-language newspaper the Atlantis, Hamill talked his way into writing his first piece about his friend, Puerto Rican professional boxer José Torres, then a neophyte middleweight and Olympic champion. This led Hamill to pursue writing a few letters to the editor for the New York Post of which two were printed. Hamill eventually attracted enough attention and was hired as a reporter for the New York Post in 1960. The 1962–63 New York City newspaper strike led Hamill to start writing magazine articles. By the fall of 1963 he was a correspondent for The Saturday Evening Post, stationed in Europe. Hamill spent six months in Barcelona and five months in Dublin, and traveled Europe interviewing actors, movie directors, and authors, as well as ordinary citizens. In August 1964 he returned to New York, reported on the Democratic Convention in Atlantic City, and was briefly employed as a feature writer at the New York Herald Tribune. He began writing a column for the New York Post in late 1965, and, by the end of that year, was reporting from Vietnam.
