Millburn, payed by Rafe Spall, is a character in the film Prometheus.
Millburn is a biologist who is a part of the Prometheus expedition. After awakening, he tries to become friends with Fifield (who rejects him). Millburn joins the initial expedition to the Engineers' artificial structure concealing the Juggernaut, tagging along with Fifield after he is upset by the number of corpses.
Separated from the rest of the expedition, they are stranded in the ship. Millburn and Fifield enter the room containing the thawed black liquid and encounter the Hammerpedes. When Millburn tries to pet one it attacks him, breaking his arm and jumping down his throat. When the crew of the Prometheus returns the next day, they find Millburn's body with the Hammerpede still in his throat.
