Actor, Dior ambassador, and now lead in Shine–learn 10 facts about Phakphum “Mile” Romsaithong, Thailand’s beloved global star and quiet power in global luxury.

In the crowded arena of Thai entertainment, few figures embody both sophistication and accessibility quite like Phakphum “Mile” Romsaithong. At once a global ambassador for luxury houses and an actor who has captured audiences far beyond his home country, Mile has emerged as a rising star and also a case study in how composure, discipline and brand alignment can translate into real influence.

The international spotlight has shifted to Thailand’s new wave of actors who are redefining what global visibility from the country can look like. And to understand why Mile has become such an essential figure in both culture and commerce, here are ten facts that shed light on the man behind the fame.

1/10 A Calm Presence Defined by Three Words

In an exclusive conversation with Koktail Thailand, Mile distilled his character into three simple Thai words: Sukhum, Noom, Mai Leuk (สุขุม นุ่ม ไม่ลึก). Translated, they mean “composed, gentle, not too deep.” By this, he explained, Sukhum reflects his steady and thoughtful nature, Noom conveys his soft-spoken and kind manner, while Mai Leuk reveals that he isn’t trying to be overly complicated, but rather someone approachable beneath his calm exterior. With a smile, he added that even his nickname, Mile, could be read as “Mild,” a play on words that encapsulates his belief in moving through life with a soft touch. 

It’s a refreshingly candid self-portrait that shows how consciously he thinks about the way people experience his presence.

2/10 Early Beginnings Rooted in Kalasin

Born on 5 January 1992 in Kalasin, a province in north-eastern Thailand, Mile grew up in the Romsaithong family, who are known for their business interests in hotels and malls. That background provided him with an early exposure to business, a subject he has later admitted continues to interest him deeply.

3/10 A Thammasat Education That Shaped His Polish

In 2017, Mile graduated from Thammasat University with a degree in Journalism and Mass Communication. This training in media literacy and communication has arguably equipped him with the rare ability to move between the worlds of entertainment, fashion and brand representation with a fluency that others take years to cultivate.

4/10 A Journey That Began Before the Screen Roles

Before acting brought him global recognition, Mile tested several avenues of performance. He took part in Thammasat University’s TU Sexy Boy showcase, worked as a DJ at PYNK 98 FM, appeared in music videos, and even attempted the reality singing competition The Star. These early explorations reveal an openness to risk and a willingness to engage with audiences in different formats.

5/10 The Breakthrough Role in KinnPorsche

Although he had appeared in smaller projects before, his role as Kinn in KinnPorsche (2022) was the breakthrough. The series was both a domestic success and a global phenomenon, triggering a five-city Asia tour and cementing his standing as a new face of Thai drama internationally. A reminder that for Mile, opportunity often meets preparation at precisely the right moment.

6/10 Man Suang and the Leap to Cinema

His big-screen debut came with Man Suang (2023), a political thriller that premiered at the Cannes International Film Festival. Sharing the screen with co-star Nattawin “Apo” Wattanagitiphat, the film grossed more than 24 million baht in its opening days.

7/10 Dior House Ambassador

In June 2023, Mile was announced as House Ambassador for Dior Thailand, a title he shares with his long-time collaborator Apo. His appearances at Dior’s Paris shows quickly drew attention, with industry reports noting that he topped the global ranking for media impact among actors during the Spring/Summer 2024 menswear season. That achievement underscored how a Thai actor can hold his own within the crowded space of global fashion.

8/10 Bvlgari’s First Male Friend of the House in Thailand

In February 2024, Bvlgari named him as the first male “Friend of the House” in Thailand, making him a forerunner for the brand in Southeast Asia. In a market where jewellery and watches are often promoted by women, Mile’s appointment reflected a new inclusivity and a recognition of his ability to embody luxury with confidence.

9/10 Expanding into Automotive and Lifestyle

His brand portfolio does not stop with fashion and jewellery. Mile has also been named Friend of McLaren Bangkok in May 2024, associating him with one of the most prestigious names in high-performance cars. Also, Penfolds appointed him brand ambassador for Thailand in October 2024, launching with the Transcend by Penfolds campaign, a partnership that demonstrates the breadth of his appeal across luxury categories.

10/10 The Reunion in Shine–A Step into History and Identity

Mile recently reunited with Apo in Shine, an ambitious new series from Be On Cloud that premiered on 2 August 2025. Unlike their previous projects, Shine is set in the politically volatile Thailand of 1969-71, giving their story deeper stakes. Mile plays Thanwa, a free-spirited hippie who believes in living with freedom and idealism, seen against the contrast of Apo’s character, Dr Trin, an idealistic economist with strong convictions. What makes Shine especially telling for Mile’s brand positioning is how it combines romance with historical weight, identity, protest and visual style–not just costume or setting, but also in the music. Mile contributed to the soundtrack (“Dawn”), giving it part of his own voice while threading the character’s energy into the soundscape.

In short, Shine goes beyond reuniting a popular pairing, Mile-Apo, it signals Mile’s growth: stepping into more complex, mature themes while preserving the composed, gentle, “not too deep” approach that defines him.
