en.wikipedia.org/wiki/Mia_Goth

This character name is contradicted by Netflix’s official materials for Guillermo del Toro’s Frankenstein. Netflix’s cast guide lists Mia Goth “as Elizabeth Lavenza and Claire Frankenstein.” A separate Tudum feature about Goth’s role also discusses her playing Elizabeth and Claire, while the same cast guide identifies Christoph Waltz as Heinrich Harlander. In other words, Harlander is attached to a different character, not to Goth’s Elizabeth. So the surname in this passage is incorrect.

This filmography entry misnames Mia Goth’s Frankenstein character. Netflix’s official cast guide for Guillermo del Toro’s film lists Goth “as Elizabeth Lavenza and Claire Frankenstein.” The same guide separately lists Christoph Waltz as Heinrich Harlander, showing that Harlander belongs to a different character. The linked article title in the post itself even points to Elizabeth Lavenza, which matches the official credits and contradicts the displayed text “Lady Elizabeth Harlander.”
