Mary Collinson and Madeleine Collinson appear together as Maria and Frieda Gellhorn in this striking color publicity photograph for Twins of Evil (1971), dressed in matching gold period gowns against a glowing red-orange studio background. Standing side by side with their hands gently clasped and their gazes turned in the same direction, the real-life identical twins create an image of near-perfect symmetry in which their extraordinary resemblance becomes the defining visual element. The result is an especially elegant and memorable piece of Hammer Films publicity built around duality, beauty and the unsettling sameness at the heart of the film.

The photograph’s appeal lies in its formal control and rich color design. The sisters are posed almost identically, each wearing a softly flowing gold dress with a fitted bodice, long sleeves and period styling that immediately evokes the film’s eighteenth-century setting. Their dark hair falls smoothly over their shoulders in nearly matching arrangements, while the luminous red-orange backdrop provides a bold contrast that separates the figures cleanly and gives the image a warm, theatrical glow. The balance between costume, pose and background makes the composition feel highly polished, with every element arranged to emphasize the twins as a matched pair.

This is a particularly effective publicity image because it reduces Maria and Frieda to their essential visual identity before the story divides them morally and emotionally. In the film, the twins’ physical sameness becomes one of its most powerful dramatic devices: Maria remains the gentler, more cautious sister, while Frieda is increasingly drawn toward the seductive influence of Count Karnstein and the corrupting world of vampirism. That contrast is not yet visible in the pose itself, which is precisely why the photograph is so successful. It presents the sisters in outward unity, allowing viewers familiar with the film to recognize how much dramatic conflict lies beneath such perfect visual harmony.

Directed by John Hough for Hammer Film Productions, Twins of Evil stars Mary Collinson as Maria Gellhorn and Madeleine Collinson—billed onscreen as Madelaine Collinson—as Frieda Gellhorn, opposite Peter Cushing as Gustav Weil and Damien Thomas as Count Karnstein. Released in 1971, the film completed Hammer’s celebrated Karnstein Trilogy, following The Vampire Lovers and Lust for a Vampire. Like the earlier entries, it draws loosely on Sheridan Le Fanu’s vampire tale “Carmilla,” while giving special prominence to the erotic and psychological tension created by the twin-sister relationship.

The publicity importance of the Collinson twins was central to the film from the outset. Their remarkable resemblance, screen presence and growing public profile made them ideal subjects for a campaign built around mirrored imagery, paired costumes and the tension between innocence and corruption. Photographs such as this one were therefore not incidental promotional material, but a key part of the film’s visual identity. The matching dresses, synchronized pose and saturated studio background all work together to present Mary and Madeleine Collinson as an inseparable yet potentially divided pair.

For collectors of Hammer horror photography, this image has exceptional value because it captures the twins in a highly stylized promotional setting rather than a dramatic scene. There is no action, no visible threat and no overt horror effect. Instead, the photograph relies entirely on the extraordinary visual power of the two sisters posed together in matching costume. The glowing color, poised expressions and elegant simplicity give the image a refined and unmistakable identity within the larger body of Twins of Evil publicity material.
