AMC Theaters has confirmed that yes, that six-minute "The Dark Knight Rises" teaser is confirmed, however, it will only be shown on 70mm IMAX screens. So what does that mean? You know those much tinier, digital fake IMAX screens Aziz Ansari was bitching about before which are kind of a total ripoff? Yeah, it will not be shown in those. Only on IMAX screens with 70mm projectors aka those constructed under the "Classic Design," because as you know, Christopher Nolan has not gone down that digital road.
Essentially, this preview is going to take some work to see as the list of 70mm capable screens is not very long. Here's an unofficial list of theaters/screens that can handle the format, but again, not all of these are IMAX and this is not a comprehensive guide.
So do your research folks and buy your tickets early if you want to see this thing. “Mission Impossible: Ghost Protocol” begins its limited IMAX-only run on December 16th before going wide on December 21st.
