To the entire Star Trek Universe, Colm Meaney will forever be remembered as The Chief. Making his first appearance in The Next Generations pilot as a background character, Meaney soon found himself in the rotating guest cast for the Next Generation as the character O’Brien was fleshed out and used to bridge the next spin off when he became part of the core cast of Deep Space Nine.
Becoming a favourite as the mild mannered transporter chief, O’Brien solidified his place in Star Trek history in Deep Space Nine thanks to Meaney bringing a grounded, working-class style into the collection of officers and diplomats around him, kicking and cursing at broken down equipment in DS9’s pilot episode and continuing to bring the most human character as a father, husband, mentor and overworked fixer of all things.

Beyond Star Trek, Meaney has had his fair share of fame and fortune outwith the final frontier as long before and after his time in the 24th century, the Dublind born actor has build an impressive body of work thanks to his natural ability to bring to life, not just the working class everyman style of O’Brien, but everything from ruthless businessmen, criminals, and even political figures showing his vast range of talents.
While Star Trek made him internationally famous, Meaney simultaneously developed an impressive film career. One of his breakthrough movie roles came in the acclaimed Irish comedy-drama The Commitments, based on the novel by Roddy Doyle. Meaney played the outspoken father of the band’s manager, helping to capture the humor and spirit of working-class Dublin. He continued his collaboration with Doyle’s work in The Snapper soon after, delivering a performance that earned widespread acclaim and a Golden Globe nomination.
One of the finest periods of his post-Star Trek career arrived in 2011 when he joined the cast of the acclaimed western drama Hell on Wheels. Meaney portrayed Thomas ‘Doc’ Durant, a ruthless railroad entrepreneur involved in the construction of the American transcontinental railroad. The role allowed him to showcase a darker, more complex side of his acting abilities. Durant was ambitious, manipulative, and often morally questionable, yet Meaney’s performance ensured the character remained fascinating rather than simply villainous. He remained a central figure throughout the series’ five-season run.
Meaney has also excelled in historical and political dramas. In the 2016 film The Journey, he portrayed Northern Irish political leader Martin McGuinness. The performance earned significant praise and won him an Irish Film and Television Award, helping to cement his already solid status as one of Ireland’s most accomplished actors.
Beyond screen acting, Meaney has maintained a successful theatre career. He has appeared in productions of classic works by playwrights such as Eugene O’Neill and Tennessee Williams, earning praise for his stage performances on both sides of the Atlantic. His dedication to theatre has helped him remain grounded in the craft of acting despite decades of screen success.
Colm Meaney’s career stands as a testament to versatility and longevity. While Miles O’Brien remains one of television’s most beloved science-fiction characters, Meaney’s legacy extends far beyond Star Trek. From Irish family dramas and Hollywood blockbusters to western epics and political films, he has consistently delivered memorable performances that have earned him the admiration of critics, audiences, and fellow actors alike.
