Peter Sproule was a British special effects technician, known for his pioneering contribution in the field of mechanical and animatronic effects. His career is inextricably linked to the *Alien* saga. For Ridley Scott's film *Alien* (1979), he was instrumental in creating the complex internal mechanisms of the Xenomorph's head. His role became even more central in James Cameron's *Aliens* (1986), where he was one of the main creators of the monumental and award-winning animatronic Alien Queen. For this extraordinary work, Sproule shared the Academy Award and the BAFTA Award for Best Visual Effects with the rest of the team. His filmography also includes other major science fiction productions, such as *The Fifth Element* (1997) and *Star Wars: Episode I – The Phantom Menace* (1999), which solidified his reputation as one of the most innovative practical effects artists of his generation.
