Nat Bush was a dancer and singer who moved from the United States to Italy in the 1960's where he resided for several decades. He also occasionally acted in films. He is mistaken frequently with New York actor Martin Sorrentino due to Sorrentino being credited as a Police Detective in The New York Ripper, while uncredited Nat Bush appeared in a much larger role as another Detective. Bush was almost never credited on Italian films due to there being a rule in place that films had to pay a larger fee to the Italian government if they hired more than one American actor in a film.
