The Bechdel Test: Amazingly, considering the setting is an ultra-bleak Crapsack World where rape is a common occurrence, it passes. Multiple times, in fact. This might explain why, at least in the West, the series has a sizable female Periphery Demographic.
Paradoxically averted in the English dub, where – due to fan demand – several of the voice actors, including the three leads* (Marc Diraison as Guts, Carrie Keranen as Casca, and Kevin T. Collins as Griffith), reprised their roles. Still, due to the fact that nearly a decade had passed since the original dub, some of the secondary roles had to be recast.
Adonis - Kathryn Kapinski was replaced with Colin DePaula
Bazuso - Patrick Tansor was replaced with Russell Nash
Gennon - Fred Velde and Rick Mann were replaced with Steve Kramer
Bosgon - Richard Springle was replaced with T.J. Storm
Fountain of Expies: Berserk has been extremely influential in Japanese fiction, to the point where Guts has become a bit of a template for "manly" characters. Caim from Drakengard, Artorias from Dark Souls, and Arngrim from Valkyrie Profile are just some of the most blatant examples.
Unrated Edition: In the case of the the third movie, Descent, some scenes were considered too erotic or too explicit for a regular theater audience (guess which) so two edits were made: the theatrical release that obscured some details and then the blu-ray release which has ALL of the details.
