One thing that every writer does is perform a ‘dream casting’ in their head. For my Gravedigger series, I’d go with actress Ana de Armas for Charity Grace. She’s beautiful and has the physicality for the role. As for Lazarus Gray, he was initially based on a young Kirk Douglas but if I had to find a modern day actor to embody the role, I’d go with actor Mark Strong. He could embody the stoic bravery that the role requires. For the Peregrine, I used to think that Nathan Fillion would be perfect but he’s aged out of the role a bit so I’d go with Oscar Isaacs at the moment.
