I've already looked at the films you should look out for in 2013. Most of them only go up to July in terms of movie posters and trailers. A lot can change from now to the middle of the summer movie season. Drastic things can move a movie out of season or year all together. The Watch and G. I. Joe from 2012 are prime examples.
However, I still like to break it down in terms of months. Let's me keep track of the movies I need to rent in the future. Let's get to the movies with "Blockbuster" status. At least in my mind.
The Grandmaster (一代宗師)
The Gangster Squad (風雲男人幫)
The Last Stand (重擊防線)
Broken City (驚爆危城)
Hansel and Gretel: Witch Hunters (女巫獵人)
Texas Chainsaw 3D (德州電鋸殺人狂)
