Oat Pasakorn Sanrattana

Oat Pasakorn Sanrattana (โอ๊ต ภาสกร สารรัตนะ) is a Thai actor whose credits run from feature films in 2014 to a lead role in the 2026 series Knot. His earliest work is in cinema. Iron Ladies Roar! is a sequel that returns to the volleyball team of the original Iron Ladies story with its members now in their forties, and Dangerous Boys came out the same year. Two more films followed in 2015, Make Me Shudder 3 and Oh My Ghost 4, so his first four credits are all films.

The year 2017 brought a larger film part in Zombie Fighters, a horror comedy in which an epidemic turns people into zombies and a group of teenage boys is trapped in a hospital. The ensemble around him included James Bhuripat Vejvongsatechawat, Biew Kittipat Samantrakulchai, Guy Korakrit Laotrakul, Tape Worrachai Sirikongsuwan and Dream Supakit Thinjun. He is also credited that year on Game of Teens, a game show and reality program on GMM 25 that began airing in February 2017 and ran 51 episodes.

Scripted television came next. He took a guest part in the second episode of 2Wish: The Series in 2019, and in 2020 he joined the main cast of So Much in Love as Jedi. The cast of six also included Guy Korrachai, Peem Supawit Tengpawadee, Strong Charoenchai Khantichaikhajohn, Mill Phumin Chaisriprasert and Jia Theeraphat Thaenkrathok. The story is set in a sports stadium in Thailand and covers friendship, family problems and haunting legends passed down over time.

In 2022 he played Keng in Oh! My Sunshine Night, a series written and directed by Ongart Singlumpong and led by Ohm Thitiwat Ritprasert as Khim and Fluke Natouch Siripongthon as Sun. The story follows Khim and his sibling Rain of a real estate family and Sun, an optimistic guitarist, and Oat’s part was a guest role in two episodes. In 2024 he appeared as August in the film Moei: The Promised, which follows a mother trying to save her son from a mystical curse, and as Win in Oh My Ghost: The Finale. From 2019 to 2024 his credits are guest, supporting or ensemble parts, which makes the step to lead in 2025 easy to trace.

That step came with My Stubborn, where he played Jun opposite Boat Yongyut Termtuo as Sorn Khansorn. The story begins with an internship that sets Jun, a pranking troublemaker, against Sorn, an orderly professional who dislikes his antics, and it moves from friction toward romance. Phusanu Wongsavanischakorn, Punn Chirathanaphat, Michelle Behrmann and Thanakrid Suteepakornchai appeared in supporting roles. A special episode set after the main story followed later in 2025.

Knot, his 2026 lead, reunites him with Boat Yongyut Termtuo, his co-lead from My Stubborn and its special episode. He plays Phatsa Rattanatharin, who grew up without knowing that alphas, betas and omegas exist until Nakhun Devathitirat, a cold and stern True Alpha and the first heir of a powerful family, unexpectedly bites him and forges a bond between them. Thee Teerawat Tanacom plays Ongsa Sirikarn and Theme Phubeth Atarunwong plays Nakhin Devathitirat, and Mflow Entertainment produced the series.

Set side by side, the two leading roles invert the same setup. Jun is the one who disrupts a composed older man, while Phatsa is the one whose ordinary life is overturned by a stern heir. The two series premiered about fourteen months apart and share both the co-lead Boat Yongyut Termtuo and the screenwriter Run Kallthypop Sciroratanaphanid. Each has twelve episodes in its main run, yet the setting changes from an office internship to an Omegaverse world, so the pairing moves into new territory instead of repeating one story.
