Source Code isn't released in Japan until 28 October but a couple of nights ago the film received its first premiere screening in the country. It sounds like Source Code was very well received and Duncan Jones has tweeted that he will be in Japan soon - for the opening? Many thanks to Rintaro Watanabe for the photo from the screening.
As is the way with film releases, as a movie opens in one country, it can already be released on DVD elsewhere. To mark the release of Source Code on DVD and blu ray in the UK, In Style has released a video which contains snippets in which Jake Gyllenhaal, writer Ben Ripley, producer Jordan Wynne and an astrophysicist explain the meaning of the source code. Watch closely - there may be a test later.
