On screen, James Bond was all icy control and razor-sharp timing. Off screen, however, Roger Moore was something else entirely—a tireless prankster who treated the set of 007 less like a sacred workplace and more like a long-running comedy experiment. And no one bore the brunt of that mischief more lovingly than Desmond Llewelyn, the actor behind Q.
Llewelyn, who portrayed the famously exasperated quartermaster across 17 Bond films, was open about one thing: he hated technobabble. The increasingly elaborate gadget explanations—packed with fictional science and rapid-fire jargon—were torture to memorize. His solution was practical and well known on set: cue cards, discreetly placed just off camera. The crew affectionately called them “Q Cards.”
Roger Moore saw opportunity.
During the production of Moonraker, while Llewelyn prepared for a particularly dense close-up explaining a deadly new gadget, Moore quietly coordinated with the crew. As cameras rolled and Llewelyn glanced toward the familiar visual aid, the expected lines were gone. In their place, three devastatingly simple words appeared:
“BALLS, Q, BALLS.”
Mid-sentence, Llewelyn froze.
Still in character, still holding the gadget, he stared in disbelief—his mind clearly racing as he tried to reconcile his dignified role with what he was now being instructed to say. Moore, standing nearby, maintained a perfectly straight Bond face. Within seconds, the illusion collapsed. The set erupted in laughter, crew members doubling over as Llewelyn realized he’d been had.
The prank became legendary, not because it was cruel, but because it perfectly captured the dynamic between the two men. Moore delighted in chaos; Llewelyn was the consummate straight man. And once Moore knew how dependent his colleague was on visual prompts, the mischief escalated.
According to Llewelyn’s own recollections, Moore sometimes went even further—collaborating with script supervisors to produce entire paragraphs of fake, nonsensical dialogue. Directors would hand Llewelyn the “revised” lines moments before shooting, claiming they were last-minute changes for legal reasons. Llewelyn would dutifully attempt to memorize the gibberish, only to discover the joke once the cameras rolled and laughter broke out.
Despite what Llewelyn jokingly called “torture,” there was genuine affection underneath it all. Moore later said that Llewelyn was his favorite co-star precisely because he committed so sincerely, even when confused. The laughter, he believed, kept the long shoots human.
That warmth bled into the films themselves. While earlier directors like Guy Hamilton encouraged Q’s irritation with Bond, the Moore era softened the relationship into something closer to affectionate bickering—part annoyance, part mutual respect.
Today, Desmond Llewelyn remains the definitive Q for generations of fans. But behind the scenes, he was also the perfect victim in one of cinema’s longest-running practical jokes—one three-word prank at a time.
