Where can I watch this Japanese movie 映画「ライトノベルの楽しい書き方」予告編 or The fun way to write light novels?

Question:

Is there any english sub?

Answer:

I am Japanese.
The DVD of movie have been sold since this March.
Although I searched many information by Google in Japanese, there are no information about English subtitles.
I don't know anything whether there are English subtitles or not.
You can buy the DVD through Japan.
But if there are not, you cannot understand what the characters say in Japanese.
I suggest that watch this movie Japanese friend who can speak English very well.
How about buying the DVD?
At least, it will never happen that you cannot watch the movie.
