In a career spanning over half a century, Bulloch is best known for his role in Boba Fett's costume in the "Star Wars" films "The Empire Strikes Back" and "Return of the Jedi", despite the character's "minimal screen time." Toby Hadoke writes that "his precise body language and smouldering presence were ... integral to the character's appeal." The voice was provided by Jason Wingreen originally and in the updated versions by Temuera Morrison, to strengthen the connection with the Prequel Trilogy. Bulloch's half-brother, Robert Watts, who was working as an associate producer for "Empire", was tasked with finding someone who "would fit in the costume of Boba Fett." So Watts called Bulloch (who at the time was working on "Agony") and encouraged him to see Tiny Nicholls, the wardrobe supervisor and Bulloch had a costume fitting as Boba Fett, which "took 20 minutes to put on."
