 With a director finally secured, the next hurdle was finishing the script, which had gone through several revisions by numerous writers.The initial villain of the film was Ernst Stavro Blofeld; however Kevin McClory, who owned the film rights to "Thunderball", obtained an injunction barring Eon Productions from using the character of Blofeld or his international criminal organisation SPECTRE, which delayed production of the film further.The villain was later changed from Blofeld to Stromberg so that the injunction would not interfere with the production.
