Thanks; I don't know where I saw it. But what I recall was that he said the cast/crew goofed off and that it seemed less professional than the Trek guys. I dunno maybe it was an interview with Paul Winfield. Or my memory is shot.
Well, JMS did say that laughter was a sound you heard a lot there.
Perhaps ther was an interview in the B5 magazine? At some point I'd like to catalogue just what's in each of them since it was always much more than showed in the Contents listing. Some day when I've got more round tuits.
