Another Earth by Mike Cahill
Melancholia by Lars Von Trier
Two of the best films I've watched this year. When you read the plot of both of them, you may think you're gonna watch the typical science fiction film. The really great thing from these films is not their original sci fi story, but the strong female leading characters and the awesome images that both of them have. Kirsten Dunst and Charlotte Gainsbourg give us a wonderful performance in Melancholia, and Brit Marling gives you the chills in Another Earth in her scenes (she's one of the writers of the film too), and has an amazing chemistry with William Mapother, who has a little but heartbreaking role in the film.
If you like films with a great dramatic plot underneath a visually stunning surface, you can't miss these two films.
