The River will have wide international appeal with stars like Paulina Gaitan (Mexico), Joe Anderson (England), Luisana Lopilato (Argentina), Bruce Greenwood (Canada), Leslie Hope (Canada), Paul Blackthorne (England), Shaun Parkes (England), Daniel Zacapa (Honduras), Eloise Mumford (US), and Jeff Galfer (US). Stars like Gaitan and Lopilato are not yet well-known in the US, but they bring a strong international fan base.
Paulina Gaitan will play Jahel. Her character is a local girl with great mechanical skills. She is very skeptical of the rescue mission because she knows that nobody comes back from that area of the river, called Boiúna. Jahel only speaks Portuguese.
Outside of The River, Gaitan is known for her roles in Sin Nombre, Trade, and We Are What We Are.

We forgot Thomas Kretschmann from Germany!
