Before Daredevil: How Charlie Cox's Boardwalk Empire Role as an IRA Soldier Paved the Way to Hell's Kitchen

The Daredevil Connection That Started in Prohibition-Era Atlantic City

Before he donned the crimson horns and became the Man Without Fear, Charlie Cox was already making waves on HBO—as a charming Irish Republican Army soldier turned bootlegger on Boardwalk Empire. As detailed in Screenshot (550).png, Cox's two-season tenure as Owen Sleater in that acclaimed historical crime series didn't just showcase his range; it was the direct catalyst for him landing the role of Matt Murdock. Marvel's then-chief creative officer, Joe Quesada, had watched the show and instantly knew Cox was his number-one pick to portray the blind vigilante.

It's a casting story that feels almost too perfect. Quesada, a comic artist who drew the iconic Daredevil story arc Guardian Devil by Kevin Smith, had an innate understanding of what makes a great Daredevil. His instincts about Cox proved as sharp as Matt Murdock's heightened senses. But what was it about Owen Sleater—a man fighting for Irish independence through violence and bootlegging—that screamed Hell's Kitchen's protector?

The Parallels Between a Rebel and a Vigilante

Both Owen Sleater and Matt Murdock operate outside the law, driven by deep conviction rather than personal gain. As Screenshot (550).png highlights, when you take up armed rebellion, you're breaking laws you feel are unjust. The IRA, in its original form, was essentially an organized vigilante force fighting for national liberation. That same moral complexity—the willingness to break rules for a higher cause—runs through Daredevil's DNA. Cox himself acknowledged this throughline, bringing the same intensity and charisma to both roles.

One key difference? Owen has no qualms about killing. In a standout scene from Boardwalk Empire, he tracks down an IRA informant and dispatches him with a garrote. That ruthless edge contrasts with Matt Murdock's strict no-kill policy—but the underlying conviction that legality is secondary to justice remains a striking common thread.

The Rise of Owen Sleater: A Charismatic Rebel in Atlantic City

Set in the 1920s during Prohibition, Boardwalk Empire follows Nucky Thompson (Steve Buscemi), a political boss and crime kingpin. The series explores the immigrant experience, particularly Irish-Americans, and their rise from discrimination to power. Cox's Owen Sleater arrives in Season 2 as an emissary from the IRA, sent to broker a liquor deal with Nucky. But he quickly becomes more than just a business partner—he falls into an affair with Nucky's Irish wife, Margaret (Kelly Macdonald).

Screenshot (550).png notes that Cox's charming performance was so compelling that it not only proved he could hold his own against actors like Buscemi but also caught the eye of Marvel executives. Interestingly, the love triangle between Owen, Margaret, and Nucky mirrors another famous dramatic triangle: that of Furio Giunta and Carmela Soprano in The Sopranos. While Furio only brushed the edge of an affair, Owen and Margaret fully consummate their relationship—leading to tragic consequences. In Season 3, Owen is killed while attempting to assassinate crime boss Joe Masseria. His corpse is sent back to Nucky and Margaret in a box, a gruesome end reminiscent of the film Se7en.

The Irish Identity in Boardwalk Empire

Boardwalk Empire was created by Terence Winter, a Sopranos veteran, and the thematic overlap is undeniable. But where The Sopranos explored late-20th-century Italian-American malaise, Boardwalk Empire dives into the roots of organized crime and the immigrant experience—specifically Irish-American. Nucky and his brother Eli are first-generation immigrants who used political machines to escape WASP discrimination. Margaret, born in Ireland, fled after becoming pregnant and being threatened with a Magdalene Laundry. Her attraction to Owen isn't just physical; it's nostalgia for a home she left behind.

The series contrasts this with the 'old country' IRA factionalism. As Screenshot (550).png explains, Owen belongs to the original IRA that fought against complete British colonial rule. By the time he arrives in Atlantic City, the Irish Civil War is brewing between pro- and anti-treaty factions. Owen's decision to stay and work for Nucky may be as much about avoiding that bitter conflict as it is about making money.

The Casting Coup That Changed Marvel History

When Netflix and Marvel were casting Daredevil in 2014, the role required an actor who could embody both a brilliant lawyer and a brutal vigilante, all while maintaining a moral core. Joe Quesada's insistence on Charlie Cox came from watching him navigate Owen Sleater's complex loyalties and romantic entanglements. Cox proved he could be both charming and dangerous, vulnerable and resolute—exactly what Matt Murdock needed.

Interestingly, Cox is English, playing an Irish rebel fighting against British occupation. Screenshot (550).png wryly notes that his performance is so good viewers can almost forgive that casting choice. It's a testament to his ability to disappear into a role, a skill that would define his Daredevil for years to come.

A Brief but Memorable Tenure

Owen Sleater appears only in Boardwalk Empire's second and third seasons (2011-2012). Yet his impact is lasting. The character embodies the show's exploration of violence, identity, and the blurred lines between criminal and revolutionary. For Cox, it was a springboard to superhero stardom. For viewers, it's a reminder that before the red suit, there was a man in a suit and tie, carrying a crate of illegal liquor, fighting for a cause he believed in—and playing a love triangle that ended in tragedy.

The legacy of Owen Sleater lives on not just in Boardwalk Empire fandom but in the very DNA of Charlie Cox's most famous role. As Screenshot (550).png makes clear, the two characters share a throughline of righteous lawbreaking, even if their methods differ. It's a fascinating piece of Hollywood history that connects a Prohibition-era drama to the gritty streets of Hell's Kitchen.

Why Boardwalk Empire Remains Essential Viewing

For fans of historical dramas, Boardwalk Empire offers a rich tapestry of 1920s crime, politics, and immigrant struggles. The show dives deep into the formation of organized crime in America, using real historical figures like Al Capone, Lucky Luciano, and Meyer Lansky alongside fictional creations like Nucky Thompson. Its exploration of the Irish-American experience is particularly nuanced, showing how immigrants used violent means to carve out power.

Charlie Cox's Owen Sleater serves as a window into the IRA's role in that world. As Screenshot (550).png highlights, the character is part of the original IRA, fighting before the partition of Ireland. The show doesn't romanticize the violence; it shows the costs. Owen's death is sudden and brutal, a reminder that in this world, no one gets a happy ending. It's that unflinching realism that made Boardwalk Empire a critical darling and a perfect showcase for Cox's talent.

For Daredevil fans, watching Cox's performance in Boardwalk Empire offers a unique perspective on his acting range. You can see the seeds of Matt Murdock's righteous anger and romantic vulnerability in Owen Sleater. It's a prelude to the star-making turn that would define a generation of Marvel storytelling.
