When Jeri Ryan joined Star Trek: Voyager in 1997 as Seven of Nine, many fans assumed the producers had brought her in simply to boost ratings with a striking new character.
They weren’t entirely wrong.
At the time, Voyager was struggling, and the network wanted someone who could bring viewers back. Seven of Nine—a former Borg drone learning how to become human again—was introduced at exactly the right moment.
The gamble worked.
Ratings jumped dramatically, but what surprised audiences most wasn’t her appearance—it was her performance.
The Character That Changed Everything
Seven of Nine quickly became one of the franchise’s most complex characters.
Behind her cold, logical exterior was someone trying to rediscover emotion, identity, and humanity after years as part of the Borg Collective.
Jeri Ryan brought unexpected depth to the role, especially in episodes where Seven struggled with conflicting personalities and emotions. Many fans still consider her one of the finest actresses ever to appear in a Star Trek series.
She Turned the Role Down… Four Times
Ironically, Ryan almost never became Seven of Nine.
When producers first approached her, she admitted she had never watched Star Trek. After finally seeing an episode, she reportedly wasn’t impressed and initially declined the offer several times.
Only after speaking with executive producer Jeri Taylor and learning more about the character did she agree to join the series—a decision that ultimately transformed her career.
Behind-the-Scenes Tension
Ryan’s arrival also created tension behind the cameras.
Captain Janeway actress Kate Mulgrew later admitted she struggled with the network’s decision to introduce a highly sexualized character while she had worked hard to make the show focus on strong storytelling rather than appearance.
For years, the relationship between the two actresses remained strained.
Eventually, however, Mulgrew publicly apologized, praising Ryan’s performance and acknowledging that she had made the situation more difficult than it should have been.
Today, the two frequently appear together at conventions, proving that old disagreements can be left behind.
The Costume Fans Never Saw Up Close
Seven’s famous catsuit looked sleek on screen, but wearing it was another story.
The tight costume made breathing difficult, required help from the wardrobe department every time Ryan put it on, and even simple bathroom breaks became lengthy production delays.
Crew members jokingly referred to those breaks as “Code Jeri-Twenty.”
By the time filming ended, Ryan had one goal in mind.
She reportedly burned the costume so she would never have to wear it again.
Acting Against… Nothing
Like many science-fiction actors, Ryan spent much of her time performing scenes that relied entirely on visual effects.
Whether reacting to invisible force fields or imaginary aliens standing in front of green screens, she often had to act with nothing there at all.
Cast members later joked that “force field acting” became one of the funniest parts of working on Voyager, even if it looked completely ridiculous before the special effects were added.
Why Fans Still Love Seven of Nine
More than two decades later, Seven of Nine remains one of the most beloved characters in the entire Star Trek universe.
She wasn’t simply introduced to increase ratings.
She challenged the crew, created meaningful conflict, and allowed the series to explore themes of identity, freedom, and what it truly means to be human.
Like Spock and Data before her, Seven became the outsider through whom audiences could better understand humanity itself.
For Jeri Ryan, it became the defining role of her career.
And for millions of fans, Seven of Nine remains one of the greatest characters Star Trek has ever created.
