She was initially told the role was “mad” because she was blond and fair-skinned, while the character from the book was described as dark with “slightly Arabic” features. Despite this, her portrayal became definitive for a generation. She also voiced an alternate-universe version of Trillian, characterized as “blonder and more American,” in the radio series’ “Quintessential Phase.” The original series has its own Wikipedia entry covering its production and cast.
