Fan CastingMany Waters

One snowy winter day, Sandy and Dennys Murry want nothing more than to be someplace warm and not too crowded. However, playfully typing these into their parents' experimental computers sends them back in time to before the flood--shortly before the flood, in fact, when manticores and mini-mammoths walk the earth, unicorns go in and out of being like virtual particles, and a man named Noah lives with his family by a desert oasis.
Remember those normie twin brothers of the girl from A Wrinkle in Time? Yeah, this is their adventure.

Since the story of Noah's Ark comes from Genesis, I'm trying to cast actors of Jewish faith and/or heritage as Noah's family and Tiglah's family.
