Massimo De Rita, who worked as a unit manager for Galatea, spent time on the set of "Caltiki" and opined that "at 90 percent Bava was also the director of "Caltiki". Freda was away, he didn't know anything about what Bava was contriving." De Rita noted that Bava told actors what to do and that Bava shot all the connecting shots with the monster and all the death scenes. Ministerial papers also note the Bava and Freda's roles in the film. The final balance in the film assigns Freda 5,000,000 lire, instead of the initial 6,000,000 and that Bava was paid 6.250 million lire, instead of his initial 3,000,000.
