They were there making the xenomorph. This is a creature that they have so much love for. We had puppeteers working on the face-hugger. So to see that – it all felt so alive,"
"I had to turn off my 'nerding out' brain, because I was just like, 'Wow, it's beautiful. Ooh, you put the Giger skull...' I had to turn that off. But it was properly scary. We set it between the first movie and the second. We were talking about, 'How could this be a child of the two?' So we have those heightened moments, but then proper horror."
"I definitely did everything that I could to bring that character to life. Watching Sigourney play that role – she's part of the changing of the game that those films did," Spaeny continues. "I could never be her. But I injected whatever I have in me into that character, and tried to make it three-dimensional – as three-dimensional as possible. So I hope that that's there, and it comes alive."
