- "Atmosphere is 71 percent nitrogen, 21 percent oxygen, traces of argon gas. "
- ―Ravel (from Prometheus)
After spending two years in hypersleep, Ravel and the other crew members are awakened. As the ship arrives at the surface of the planet, Ravel and his co-pilot Chance make a bet of one hundred credits about the mission either being a terraforming or an archeological expedition. When the truth of their mission is revealed during the crew's briefing, Ravel refuses to pay Chance as he reasons that Chance never made a bet about finding ancient aliens. Ravel, along with Vickers, later observe the crew during their mission to rescue Fifield and Millburn, who were trapped in the Engineer Temple during the crew's first exploration due to a windstorm.
Ravel and Chance decide to stay on board the Prometheus to help Janek stop the Last Engineer from traveling to Earth, as the Engineer plans on killing all humans by deploying its ship's cargo, the black liquid. They valiantly crash the Prometheus into the Engineer's ship, honorably dying in the process.
- In Jon Spaihts' original script for Prometheus, titled Alien: Engineers, Ravel is actually a woman named Mona Ravel, and she is part of the scientific team rather than a member of Janek's crew. In the script, Ravel is deliberately impregnated with a Facehugger by David inside the Engineer structure, dying when the Chestburster emerges from her.
