Early Life and Family Background

Séamus McLean Ross has strong ties to Glasgow, Scotland, and comes from a household closely connected to music and the performing arts. His father, Ricky Ross, and mother, Lorraine McIntosh, are both members of the Scottish band Deacon Blue.

His parents’ careers introduced him to a creative environment from an early age. However, rather than following them directly into the music industry, Ross developed an interest in acting and storytelling.

Education and Professional Acting Training

Before establishing himself on television, Ross studied at the Guildhall School of Music & Drama in London. He graduated in 2022 after receiving training in classical acting, voice, movement and stage performance.

His official Guildhall profile records experience in several theatrical productions, including Anna Karenina, Julius Caesar, Road and Dennis of Penge. He also wrote and directed a student production titled Leaving the Nest.

His training included work on Shakespeare and other dramatic texts. It helped him develop the skills required to interpret characters, communicate dialogue and perform confidently before an audience.

Ross has also credited voice teacher Patsy Rodenburg with influencing his approach to acting. In interviews, he has explained that drama school strengthened his technique, although working professionally taught him additional skills specific to acting on camera.

How His Parents Influenced His Career

Ross has spoken positively about the influence of his parents. In an April 2026 interview with Man About Town, he explained that watching his mother’s theatre performances helped inspire his love of acting.

That influence extended beyond entertainment. He described learning about artistic commitment and the importance of remaining grounded while pursuing a creative profession. His family background therefore provides useful context for his career without defining his achievements.

Early Acting Career: Payback and Rebus

Séamus McLean Ross began building his screen career with smaller roles in British television.

In 2023, he appeared as Nicky Leigh in Payback, a crime thriller featuring Peter Mullan, Morven Christie and Prasanna Puwanarajah.

The following year, he played Jack in three episodes of Rebus, the BBC’s contemporary adaptation of Ian Rankin’s Scottish detective stories.

These appearances marked an important transition from formal training to professional screen work. They also gave him experience working within established television productions before taking on larger characters.

Séamus McLean Ross in Outlander: Blood of My Blood

One of Ross’s most recognisable performances is his portrayal of Colum MacKenzie in Outlander: Blood of My Blood.

The series premiered in 2025 and explores the earlier generations of families connected to the original Outlander story.

Ross plays a younger version of Colum MacKenzie, a character originally portrayed by Scottish actor Gary Lewis.

Who Is Colum MacKenzie?

Colum belongs to the influential MacKenzie family and is closely connected to the political struggles of the Scottish Highlands.

His siblings include Ellen MacKenzie, played by Harriet Slater, and Dougal MacKenzie, played by Sam Retford.

The character’s responsibilities, family relationships and involvement in clan affairs create much of the tension surrounding him.

For Ross, the role offers an opportunity to explore an established fictional character at a younger stage of life. It also introduces him to the international audience associated with the Outlander franchise.

The show continued into its second season in September 2026, with Ross remaining part of the cast.

California Schemin’: His Major Film Breakthrough

Another major milestone arrived with California Schemin’.

The film marks the feature directorial debut of Scottish actor James McAvoy and tells the unusual true story of two Scottish musicians who attempted to break into the music industry by pretending to be American rappers.

Ross plays Gavin Bain, while Samuel Bottomley portrays Billy Boyd.

The real musicians formed the hip-hop act Silibil N’ Brains after encountering industry resistance to their Scottish accents.

They adopted Californian identities, eventually attracting attention from influential figures in the music business.

Preparing to Play Gavin Bain

Playing Bain required more than learning dialogue. Ross had to portray a real person who was performing an invented identity of his own.

The actor prepared through discussions about the character, musical performance and accent work. He also spent time learning about Bain’s experiences.

In interviews, Ross explained that the production required him to move between Gavin’s Scottish identity and his American rap persona.

The film premiered at the Toronto International Film Festival in 2025 and reached UK cinemas on 10 April 2026.

Its mixture of music, ambition, friendship and identity gave Ross a substantial leading role beyond television.

Career Recognition and Industry Attention

Ross received significant professional recognition in August 2024 when Screen International selected him for its Rising Stars Scotland programme.

The initiative, organised with Screen Scotland, highlights emerging performers and filmmakers with the potential to develop international careers.

The selection placed him among a group of promising Scottish creative professionals and offered further industry exposure.

British Independent Film Awards Recognition in 2026

On 14 October 2026, Ross appeared on the British Independent Film Awards longlist for Breakthrough Performance.

The recognition was for his portrayal of Gavin Bain in California Schemin’.

This is an important distinction: Ross was longlisted, but had not yet been announced as a final nominee or winner as of 16 October 2026.

The recognition adds to the attention surrounding his feature-film performance and represents another notable step in his career.

Disco Pigs: A Major Theatre Role in 2026

Ross is also returning to the stage in an important revival of Disco Pigs.

He has been cast as Pig opposite Aoise Meaney as Runt in the play’s 30th-anniversary production at The Everyman in Cork.

Written by Enda Walsh, Disco Pigs originally premiered in 1996 and helped launch the careers of Cillian Murphy and Eileen Walsh.

The story follows two teenagers whose intense friendship and shared private language become increasingly difficult to sustain as they approach adulthood.

Walsh is directing the new production himself.

The performances are scheduled from 31 October to 14 November 2026, with the official opening on 6 November.

An interesting detail emerged in an October 2026 Irish Examiner interview: Ross and Meaney share the same date of birth, 26 November 2000, just as their characters share a birthday in the play.

For Ross, the production represents another demanding character role and an opportunity to continue developing his stage career.

Upcoming Film Project: Bare

Séamus McLean Ross is also part of the cast of Bare, a film directed by Lorna Tucker.

The project is based on Tucker’s memoir and features an ensemble including Florence Hunt, Isla Fisher, Colin Firth, Ruaridh Mollica and Mirren Mack.

The production was announced as filming in London in April 2026.

Although Ross’s involvement has been confirmed, detailed information about his character and a final release date has not been established in the available official announcements.

The film extends his experience into another type of screen production following his work in historical drama and music-based filmmaking.

Personal Interests and Life Outside Acting

Outside his professional career, Séamus McLean Ross has spoken about his strong connection to Glasgow and Scottish culture.

He supports Dundee United Football Club and has discussed attending matches with his family.

Football is another connection with his father, whose Deacon Blue song Dignity has become associated with Dundee United supporters.

Ross has also expressed an interest in music, spending time outdoors and exploring Glasgow.

His Guildhall profile lists singing and advanced drumming among his performance skills, demonstrating that music remains part of his creative abilities even though acting is his primary profession.
