In Frankenstein, Mia Goth plays Victor's mother and his love interest. Here’s how she pulled it off.

This isn’t exactly a subtle move. Del Toro seems to be making a clear point about Victor’s state of arrested development. Despite his incredible intelligence and skills as a surgeon, he’s still just a little boy in love with his mother. That metaphor pops up throughout Frankenstein, and it’s reflected in the costumes and prosthetics used to help differentiate Goth’s two characters, the ethereal Baroness Claire Frankenstein (Victor’s mom) and the enchantingly odd Lady Elizabeth Harlander (his brother’s fiancée… it’s complicated).
