  • This version of Isabelle only appeared in the film adaptation The Mortal Instruments: City of Bones, portrayed by Jemima West. Though the character was minimally changed, it was not explored beyond the film. Some of the few notable differences from the book(s) include:
    • Isabelle had blue eyes in the film instead of her dark brown eyes in the books.
    • In the film, Isabelle was never called "Izzy", a nickname frequently used to refer to her in the books.
