1. William Shatner Endures
William Shatner became a household name in 1966 when he starred as Captain James T. Kirk in Star Trek. At a time when science fiction was still new to television, his confident and energetic performance helped define the genre. When the series ended in 1969, many expected Shatner’s fame to fade. Instead, he steadily rebuilt his career across television, film, and writing. His major resurgence came with Boston Legal, which aired from 2004 to 2008 and earned him awards and critical praise. Beyond acting, Shatner hosted documentaries, recorded music, wrote bestselling books, and remained active at fan conventions. Even into his 90s, he continued public appearances, showing remarkable longevity. His constant presence over more than five decades helped keep Star Trek visible in popular culture.
2. Leonard Nimoy’s Lasting Impact

He directed Star Trek III in 1984 and the highly successful Star Trek IV in 1986, both of which strengthened the film franchise. He also directed mainstream hits such as Three Men and a Baby. Outside film and television, Nimoy explored poetry, photography, and memoir writing. Before his death in 2015, he returned as Spock in later films, serving as a bridge between classic and modern Star Trek audiences.
3. DeForest Kelley’s Quiet Strength
DeForest Kelley portrayed Dr. Leonard “Bones” McCoy in Star Trek from 1966 to 1969. His sharp wit and emotional honesty gave the series a strong human centre, often grounding its more futuristic ideas. Before Star Trek, Kelley spent decades as a dependable character actor, especially in Westerns and crime dramas during the 1950s. When Star Trek expanded into films starting in 1979, Kelley returned, appearing in all six original-cast movies through 1991. After that, he largely stepped away from acting, choosing privacy over publicity. Despite his quieter post-Star Trek life, his contribution remains vital. McCoy’s compassion and humour helped balance Kirk’s leadership and Spock’s logic, making the original crew feel real and emotionally connected to audiences.
4. Nichelle Nichols Breaks Barriers
Nichelle Nichols made television history in 1966 as Lieutenant Uhura in Star Trek. At a time when Black women were rarely shown in professional roles on television, Uhura stood as a symbol of equality and progress. Her presence reflected the social changes taking place during the civil rights era. In the late 1970s, Nichols worked closely with NASA, helping recruit women and minority astronauts, including those who later flew on space shuttle missions. Although she appeared less often on screen later in life, she remained an influential public speaker and fan favourite at conventions worldwide.

He often addressed his Star Trek fame with humour, embracing audience recognition. In Star Trek: Picard, Spiner returned to the universe, adding emotional depth and closure to Data’s story.

After the series ended in 1994, Sirtis continued acting in television, film, and voice work, often returning to science-fiction and fantasy genres. She also reprised her role in Star Trek films and later series appearances.

Sirtis’ lasting connection with audiences reflects how Star Trek performers often maintain strong relationships with fans long after their original episodes aired.

Already well known for Roots, Burton brought intelligence and warmth to the role of Starfleet’s chief engineer. Geordi became a symbol of technical skill and perseverance.

Phillips’ performance shows how supporting characters in Star Trek often grew in importance through consistency, patience, and thoughtful acting rather than immediate popularity.
