Yes, Aron Eisenberg, who plays Nog in Star Trek Deep Space Nine came for a Trekkie conference to London in May 2001 and stayed at my gaff for a night. I was a bit mashed in the photo, having just got back from 10 days in Luxembourg, filming in a muddy trench with 200 Eastern-European extras, but the pint-sized star was very charming and agreed to pose with me in my garden. I have never watched a single episode of the series, but am informed by my obsessed brother that Aron is the most recurring guest star in the show. A lovely geezer. He has his for friends of the show.
