down Sergio Leone's A Fistful of Dollars and recommended Clint Eastwood for the role. Harrison joked that this was his greatest contribution to cinema. The 1968 film Joko - Invoca Dio... e muori Vengeance, directed by Antonio Margheriti, is another favorite among Spaghetti Western fans. Luciano Martino's 1965 movie Secret Agent Fireball, Harrison's first Eurospy film, is also often cited as his best film in the genre, and one of his better earlier films. He again played the role of CIA Agent Fleming in a sequel Killers Are Challenged in 1966. The Italian actor Bruno Piergentili who made European features during this period was given the name "Dan Harrison", perhaps to evoke Richard's name. 1970s exploitation films Harrison's career dwindled slowly in the 1970s at the same rate as the Spaghetti Western died. He began appearing in low-budget movies shot all over the world: In Egypt (You Can Do a Lot with 7 Women (1971), with the Shaw Brothers in Hong Kong starring in the title role of Marco Polo (1975) and playing the German commander von Waldersee in The Boxer Rebellion (1976).
