Aniplex USA's official twitter account announced just minutes ago that the first two movies in the upcoming trilogy of Madoka Magica movies will run in US theaters this October. The first two films, Puella Magi Madoka Magica the Movie Part I: Beginnings and Puella Magi Madoka Magica the Movie Part II: Eternal will be shown in select US theaters as a double feature just days after the Japanese release date.
The films will recap the happenings of the television anime series. They are being distributed by Eleven Arts who also brought Trigun: Badlands Rumble and Evangelion 2.0 to US theaters. It's safe to assume that the film will be shown with the original Japanese audio and English subtitles.
At the time of writing this, the websites for the theaters that are scheduled to show the film have not yet been updated to include film information or ticket sales. Currently the film is scheduled to run in Los Angeles, San Francisco, Houston, Chicago, and New York. You can find a full list of theaters showing the film on the series' official English website.
