The series' arrival in the English-speaking market was delayed by NBC Enterprises executives' perception that it could be interpreted as "sex switch". However, still in the 1970s, the television series got a dubbed version produced by Joe Oriolo. Renamed "Choppy and the Princess", it was released to American, Australian, and British television audiences, with home video releases to follow. The manga would only reach the anglophone public years later, in 2001 when Kodansha International published a bilingual edition of "Princess Knight", which was followed by a newer version by Vertical in 2011.
