Just saw it at the Prince Charles Cinema (London)!
It played tonight in a double bill with Reservoir Dogs. The Prince Charles (awesome independent cinema) is doing a 'QT Season' where they screen Tarantino's films side-by-side with some of his own favourite movies.
Anyway, Rolling Thunder was great! Lovely to see it on a big screen. A small, but appreciative audience. Everyone laughed or winced at a few moments, and there was a round of applause at the end.
I'd been wanting to see it for ages. Really glad I did!
