Arm Weerayut Chansook

Arm Weerayut Chansook got into the business through a microphone. In 2007 he finished first runner-up in the Luk Thung Star Contest, went to singing school, and in 2010 signed with RS, where he joined the boy band Rookie BB. The acting came six years later, and these days he is just as likely to be holding the microphone as a host.

He went to Phrapathom Wittayalai School and in 2015 graduated from the Faculty of Fine Arts at Srinakharinwirot University, with a degree in acting and directing. His Rookie BB bandmates were Pop Supasit Chinvinijkul and Iang Sittha Sapanuchart, who is in the cast of Identity Zero.

He joined GMMTV in 2016 and debuted as San in Senior Secret Love: Bake Me Love. He played Him in several U-Prince segments and Putt in Water Boyy (2017). The year 2018 brought Oat in Mint To Be and Tawan in Love at First Hate. In 2020 he played Pop in Friend Zone 2: Dangerous Area and Jonathan, called Jo, in Wake Up Ladies: Very Complicated, and a year later he was Bomb for sixteen episodes of 55:15 Never Too Late.

The past three years have put him in a run of BL and GL ensembles. He was Oh, a guest in five episodes of We Are, and Ton in the GL series Pluto (2024), then Prem in My Romance Scammer and Ming Thiticharoen in Match Point (2026). Hosting runs alongside the acting, and his own lifestyle show Arm Share has passed two hundred episodes since 2019.
