There are a lot of different genres so I think everyone will find something they are excited about! Here are my recommendations:
If you love Garden State and Zach Braff's strangely awesome story telling. You might be interested in Wish I Was Here. I'm pretty interested to see him and Kate Hudson being parents together. Crazy!
If you are into movies about a musician's journey and/or you loved the musical movie Once.
You will probably enjoy this new movie by the director of Once, with Keira Knightley and Adam Levine, Mark Ruffalo and a slew of other people. It goes without saying that I'm really excited about this soundtrack!
Also if you are a fan of Emma Stone and/or Colin Firth (and who isn't) you might be willing to sit through this Woody Allen period story, Magic in the Moonlight. Which looks totally adorable :)
And finally if you like cartoons at all, you might find this latest offering from Disney: Big Hero 6 which is about superheros recruited to protect the nation. I just really enjoy the robot not coming out like the inventor has envisioned ( I have a similar process when I am making prototypes: what looks good on paper vs. what a two dimensional creature actually turns out like lol )
What about you? Any new movies coming out that you are super excited about?
