Alienoid—directed by Choi Dong-hoon and starring Ryu Jun-Yeol, Kim Woo-bin, and Kim Tae-ri—is the first in a planned series of two epic sci-fi action time-warpers. A tale of two eras, Alienoid follows two Goryeo Dynasty (918-1392) shamans seeking a legendary, time-bending blade as they unexpectedly cross paths with modern-era people hunting down a dangerous alien concealed inside a human's body.
