Many thanks to @etsuko0704 for sharing on twitter
Hiroyuki Sanada was interviewed on a Japanese TV show. N etsuko has shared a clip of Mr. Sanada’s interview on youtube. The clip shows some footage from the 47 Ronin world premiere, pieces of the trailer before the interview starts. The interview is in Japanese and there are no English subtitles. However, there is some behind the scenes filming footage interspersed through the interview.
The clip is here.
