First, the actor exuded charisma and showed off intense action scenes as the Guard who manages the transfer of alien prisoners. Moreover, Kim Woo Bin had to act using motion capture in order to film a sequence where he transforms into a robot, providing a diverse attraction. Additionally, he got dressed up in pink attire as Thunder, GuardŌĆÖs sly and delightful partner disguised as Guard, and showed unexpected cuteness as ŌĆ£model studentŌĆØ Thunder. And unlike Guard, whoŌĆÖs determined not to engage in human affairs, Thunder has an odd interest in humans. So through this alternate character, Kim Woo Hin delicately portrayed the changes in the emotions of Guard, who had lived on Earth for a long time, escorting and managing alien prisoners. Meanwhile, Alienoid Part One follows a group of Taoists from the Goryeo dynasty who mistakenly open a time portal in search of a legendary sword. The portal connects them to humans from 2022, who are tasked with finding an extraterrestrial prisoner locked in a human body. Ryu Jun Yeol, Kim Tae Ri, Kim Woo Bin, So Ji Sub, Jo Woo Jin, Kim Eui Sung, and more starred in the movie. Source: CJ ENM
