I'm looking forward to Darkness, My Old Friend. That isn't coming out, but it is constantly playing in my room ;p
The last movie I saw in theaters was Nacho Libre. I'm hyped for RetroKaiser: The Movie, but that isn't a major release and I'm sure that doesn't count to your question.
To give a legitimate answer, there isn't a single movie coming out that I'm excited to see. My desire to see any of it died during the hype train of Guardians Of The Galaxy.
