Noomi Rapace as Elizabeth Shaw, an archaeologist.
Charlize Theron as Meredith Vickers, an employee of Weyland Corporation. From the description of the movie, it seems like Noomi Rapace’s archaeologist is a more important character than Theron’s possibly evil corporate tool, but I notice that a lot of the marketing of the movie is focused on Theron. Makes sense, I guess, since Theron is probably the bigger star in Hollywood, but a little disappointing nonetheless.
Michael Fassbender as David, an android. What IS that red heart-looking thingy??
Idris Elba as Janek, the ship captain. He’s always in normal clothes instead of the space-wardrobe in all the pictures I’ve seen. I guess the captain has to stay on the ship, instead of going out exploring. Hopefully that means he wouldn’t be among the first to die, heh.
Logan Marshall Green as Holloway, a scientist. I think this is the guy holding hands with Noomi Rapace after finding the drawing in the cave in the trailer. Possible love interest to the heroine, but doesn’t seem to be the main male character himself – my money is on this guy to be the first to die.
