Not sure these will all count as 2012, but are recent (I saw them this year).
1. Shame 2. We Need To Talk About Kevin 3. The Master 4. The Impostor 5. Berberian Sound Studio 6. Searching for Sugar Man 7. Tabu 8. Argo 9. The Dark Knight Rises 10. Prometheus (mainly for the Fassbender and Rapace performances, but enjoyed it as silly fun without getting upset about the plot craters)
