Puppeteering Project Hail Mary

When I interviewed Andy Weir in 2021 about his novel Project Hail Mary, he told me that the movie adaptation was already being planned starring Ryan Gosling. The big question was how would they bring the alien character of Rocky to life. Would they use CGI or practical effects? Now that the film is in theaters, we have the answer. While there is some use of digital effects, Rocky is mostly performed by the puppeteer James Ortiz. James has a deep background in theater but he had never worked on a film before, let alone a sci-fi blockbuster. I talked with James about the delicate balance of operating an incredibly sophisticated five-legged puppet while giving Rocky a distinct personality and building a rapport with Ryan Gosling, who relies heavily on improvisation.
