I saw Moon last night in preparation for an onstage interview I'm hosting with the film's director Duncan Jones at the BFI Southbank tomorrow night, and all I can say now is that it's a quite brilliant piece of filmmaking, one that marks the arrival of a major, major directing talent. Smart, tense, with a terrifically contained script by Nathan Parker and a wonderful performance from Sam Rockwell, it is, however, almost impossible to talk about without spoiling. So, instead, you should go see it when it's released in the UK on July 17.
Tomorrow's screening and Q&A is sold out but very often there are returns on the night. If you're going, hope to see you there. If not, I'm sure they'll have the interview up on the BFI Southbank website soon enough.
