Her next acting role was the film Hacker's Game (2015), in which she plays a hacker she compared to Lisbeth Salander from the novel The Girl with the Dragon Tattoo.
She continued taekwondo after the film, and has a purple belt as of the summer of 2014. Klementieff moved to Los Angeles after Oldboy was filmed and began pursuing more Hollywood auditions. Klementieff came up with the name Haeng-bok, Korean for "happiness", herself after Lee asked her to research possible names for the character. She contributed some of her own clothes to the character's wardrobe, and trained three hours a day for two months for an on-screen fight with star Josh Brolin. After showcasing her boxing skills during her audition, Lee asked her to go home and come back wearing a more feminine outfit and make-up, like her character in the film. A fan of the original film, Klementieff heard about the part through Roy Lee, a producer with the remake, and took boxing lessons after learning the role involved martial arts. She portrayed Haeng-bok, the bodyguard of the antagonist played by Sharlto Copley. Klementieff made her Hollywood debut in Spike Lee's Oldboy (2013), a remake of the South Korean film of the same name. During filming she befriended nomads who lived there, worked with real wolves, rode reindeer, and swam with a horse in a lake.
During filming, Klementieff stayed in a camp, hours from the nearest village, where temperatures dropped well below zero. Her first leading role was in Loup (2009), a French film about a tribe of reindeer herders in the Siberian mountains. During one scene, Klementieff was supposed to push someone down a set of stairs but accidentally fell down the stairs herself, and director Gaël Morel kept that shot in the final film.

A few months into her education, she won a theatre competition that awarded her free classes for two years with the school's top teachers. She started acting at age 19 at the Cours Florent drama school in Paris. She also worked as a waitress and saleswoman in France. Klementieff briefly attended law school after her uncle's death to appease her aunt but did not find the career path appealing. Her uncle, whom she described as "like second father", died on her 18th birthday, and her older brother died of suicide seven years later, on her 25th birthday. Klementieff's father died of cancer when she was five, and her mother had schizophrenia and was unable to care for children, so Klementieff was raised by her paternal uncle and aunt. They lived in Japan and Ivory Coast, before settling in France.
Klementieff lived in Canada for one year before her family began travelling extensively due to her father's job. Her parents chose the name "Pom" because it is similar in pronunciation to the Korean words for both "spring" ( 봄) and "tiger" ( 범). Her grandfather was the Russian painter Eugene Klementieff. She is a French citizen, and does not have Canadian citizenship because jus soli does not apply to children of diplomats. Pom Klementieff was born in Quebec City, Quebec, Canada, to a Korean mother and Russian- French father Alexis Klementieff, who was working there as a consul with the government of France.
