Greenwood will be portraying Doctor Elvi Okoye on the series, a biologist intent on studying samples from New Terra to determine the true nature of the planet.

Syfy had cancelled The Expanse this past May after three seasons, citing low ratings and high production costs despite its critical acclaim. By the end of the month, Amazon had picked up the series for a fourth season with executive producer Naren Shankar noting that the show no longer had content restrictions and would film natively in 4K UHD.
