James Cameron and Aliens are often mentioned together for reinventing science fiction cinema, but bringing Sigourney Weaver back to the sequel was a significant challenge that required determination and creativity. Cameron recently detailed how he managed to persuade Weaver, known for her anti-gun stance, to reprise her role, shaping the film into a pivotal moment in the genre.
Cameron’s Early Steps and Sigourney Weaver’s Pivotal Role
Following the success of Ridley Scott’s Alien, James Cameron began preliminary work on its sequel, Aliens. At the heart of the new story was Weaver’s character, the only survivor from the original film. Despite being deep into the pre-production process, Cameron realized no one had discussed the role with Weaver herself, whose participation was essential. He said,
“But the funny thing was, I’d already gotten into, now we’re in pre-production on Aliens, and nobody’s talked to Sigourney,”
—James Cameron, Director.
Cameron was working under the assumption that Weaver was bound to the project through an option contract, but he soon learned that a condition known as the seven-year rule made the option unenforceable. This drove Cameron to personally meet Weaver in Santa Barbara to ensure her involvement. As he explained,
“I had gone into it and signed a deal, and everything on the principle that Sigourney was under an option. But there was this thing called the seven-year rule, and the option was unenforceable. So I drove up to Santa Barbara to meet her,”
—James Cameron, Director.
Building Trust and Navigating Creative Differences
During that meeting in Santa Barbara, Cameron was struck by Weaver’s intelligence and warm disposition. Their conversation proved productive, laying the foundations for their collaboration on the ambitious sequel. Cameron recalled,

“She was living up there at the time. And we had this great meeting. And she was just so sweet and so intelligent, and we just clicked,”
—James Cameron, Director.
However, challenges arose during filming. Weaver, committed to advocating against gun violence, was surprised by the inclusion of heavy weaponry in the script. Cameron shared her concern,
“So Sigourney shows up on set, and she says, ‘What’s all this with me firing machine guns? I’m a gun violence anti-gun advocate,’”
—James Cameron, Director.
Realizing the importance of her comfort with the role, Cameron encouraged Weaver to thoroughly review the script, particularly the action sequences in the third act.
“She said, ‘Well, I read the dialogue.’ I said, ‘You might wanna go back and read the pro section in act three.’ So I took her out back behind the studio in Pinewood in England, and I put a Thompson machine gun in her hands, blank rounds, and said, ‘Try this,’”
—James Cameron, Director.
Turning Point on Set and Enduring Impact
The experience at Pinewood Studios proved transformative. After handling the Thompson on set, Weaver’s outlook shifted. Cameron recounted the moment:
“And she looks at me and says, ‘Oh, that’s kinda cool.’I said, ‘That’s what you have to do.’ And she said, ‘All right,’”
—James Cameron, Director.
This breakthrough was crucial, allowing filming to continue with Weaver fully embracing the physically demanding aspects of her character. James Cameron’s approach and Weaver’s eventual agreement helped create one of science fiction cinema’s most memorable sequels. The collaboration underscored Cameron’s inventive direction and Weaver’s commitment to her craft, solidifying the legacy of Aliens as a landmark in the genre.
Looking back, the partnership between James Cameron and Sigourney Weaver on Aliens not only advanced the story of Ripley and expanded the universe conceived by Ridley Scott, but also demonstrated the power of creative problem-solving when strong personalities and principles meet on set. This pivotal moment at Pinewood ensured the film’s success and lasting influence in science fiction film history.
