Wingfield has appeared in numerous North American television productions for both Canadian and U.S. companies, including the portrayal of Dr Robert Helm in Queen of Swords filmed in Spain at Texas Hollywood, Almeria, and the surrounding Tabernas Desert. Executive Producer, David Abramowitz, met Peter Wingfield at a Highlander convention in November 1999 and offered him the parts of Doctor Helm or Captain Grisham. Wingfield chose the Doctor as a part with more mileage and more challenging.
