I went to the Star Trek: Into Darkness premiere in London last Thursday and the whole cast and JJ Abrams were amazing with the crowd. Chris Pine in particular seemed to sign autographs for ages. I got to see them all up close and they were happy, smiley people who really know how to get the fans on side when it comes to promotion. Met Alice Eve briefly and she was lovely.
I wish I could get to premieres more often. The massive ones like ST are brilliant fun.
