To play the arrogant, cynical journalist Alex Law, McGregor underwent a significant physical and stylistic shift. He swapped his natural appearance for a sharp, slightly “mod” aesthetic, slicked-back hair, dark turtlenecks, and a flamboyant, oversized overcoat. Crew members and co-stars noted that McGregor leaned heavily into the character’s wired, caustic energy. It was a stark contrast to the more romantic or period-drama roles he had touched on previously (like Lipstick on Your Collar).

The film’s success relied entirely on the chemistry between the three leads: McGregor, Christopher Eccleston (David), and Kerry Fox (Juliet). To build a believable “flatmate” rapport, the trio spent a great deal of time together off-camera. While McGregor and Fox were known for being more spontaneous, Eccleston was more Method-oriented and stayed in a darker headspace to match his character’s mental unraveling. This natural friction on set actually helped fuel the onscreen tension as the characters began to turn on one another.

Though the film is set in Edinburgh, most of the interior filming took place in a warehouse in Glasgow. The iconic, brightly colored flat was a purpose-built set. Because the budget was tight (roughly £1 million), the set was designed to be claustrophobic. McGregor often remarked on how the physical environment, the trapdoor in the floor and the attic space, dictated the frantic pace of his performance.

Danny Boyle encouraged a “high-octane” environment. He played music on set to keep the energy up, a technique that McGregor thrived on and would later become a staple of their work together on Trainspotting.

McGregor has often described Shallow Grave as the “happiest time” of his early career. He wasn’t yet a global superstar, so there was a sense of “us against the world” among the young cast and crew. “It was the first time I felt like I was part of a ‘new’ kind of filmmaking—something that wasn’t just another period piece or a social realist drama,”he said on the Shallow Grave experience.”

A pivotal moment in his look occurred in the mid-1950s. When he was around 15, his girlfriend showed him a photo of Elvis Presley. Walken was so struck by the singer’s appearance that he styled his hair to match, and famously claims he hasn’t really changed the hairstyle since.

When he wasn’t on a TV set, Ronnie was often helping out at Walken’s Bakery, the family business in Astoria owned by his German-immigrant father, Paul. There are several famous archival photos from 1955 showing Ronnie and his brothers rolling out pie crusts or having pillow fights in their Long Island home.

He didn’t become “Christopher” until 1964. A friend and fellow performer, Monique van Vooren, told him the name suited him better than “Ronnie,” and it stuck just as his adult career began to take off.

In the mid-1950s, Jones was the face of the massive widescreen musical. Because these films often featured period costumes, her “leggy” appearances were often tied to specific dance numbers or character-specific wardrobe. The 1960s saw a shift in Jones’s image, particularly after her Oscar-winning turn in Elmer Gantry (1960), where she played a more provocative character.

Like many contract players of the time, Jones participated in studio-mandated “cheesecake” photography, often posing by pools in classic one-piece suits or high-waisted bikinis. Having started in musical theater, many of her most iconic photos involve her in dance leotards or shorter stage costumes that emphasized her posture and legs. By the late 1960s, she was often photographed in the popular “mini” silhouettes, marking a stark contrast to her 1950s debut.
