My Offical TDA Fancast: Full Disclaimer: It was extremely difficult to find the right people for this and I had to use some models instead of actors but I hope you like it!
Part 1 (because I couldn’t fit them all)
Emma Carstairs: Scarlett Leithold (Model)
Julian Blackthorn: Benjamin Wadsworth
Mark Blackthorn: Niclas Gilles
Cristina Mendoza Rosales: Cindy Kimberly (model)
Kieran: Milles Mcmillan (model)
Ty Blackthorn: Asa Butterfield
Kit Herondale: Max Barczak (model)
Livvy Blackthorn: Emily Rudd
Aline Penhallow: Jacky Lai
Helen Blackthorn: Sydney Meyer
Are you kidding me? Cristina is Mexican! Mexicana!! So only a Mexican actress or model should play her.
