plum for  Harry Alan Towers (qv)) as the author of the screenplay, the Spanish  version (with a credits sequence that replaces the exterior shots of the  castle from the original with a cheesy drawing of a red dragon) lists  Manfred Barthel (qv) as the author of the story and screenplay, and  Jaime Jesús Balcázar (qv) as the author of the dialogue. This version also  credits some actors (such as Gustavo Re (qv) and Osvaldo Genazzani (qv))  and crew members not credited in the English version, and the cast order is  different as well.
