Ever since its debut on NBC in the fall of 1966, Gene Roddenberry’s Star Trek has been a cultural phenomenon. The long-running series succeeded in bringing authentic sci-fi themes and narratives to primetime television. After Star Trek: The Original Series went off the air in 1969, Star Trek has since lived on in blockbuster movies, video games, novels, and spin-off TV shows.

Roddenberry’s creation also brought to life a new segment of society: the Trekkie. Trekkies have the ability to memorize every line from every episode and dress up as their favorite member of the Starship Enterprise on the regular; some of them even learn how to speak Klingon, the fictional language of the Star Trek universe. Over the years, Trekkies have evolved from existing solely in dark basements and comic book stores to existing in the mainstream. And with the recent “geek chic” trend sweeping through Hollywood, even celebrities are coming out in droves to declare their undying love for all things Trek.

This Wednesday, at 8pm EST, The Science Channel will air a two-hour documentary titled Trek Nation, which takes a closer look at what inspired Trekkies in the first place. So to celebrate this comprehensive documentary, we’re taking a look at The 10 Hottest Celebrity Trekkies. Because that's what Gene Roddenberry would've wanted.
