How many real life Borg did you have to work with?
Because costuming was very, very expensive, one matte was used over and over. When Picard was kidnapped by the Borg it was used then. Later on, it was modified with a more expansive look. Originally, there were probably no more than about six, if that many.
Everyone knew that when it was all done this would be increased over and over and over. There would be no giveaway that there were only six Borg, because it would look like thousands when it was finished.
Did the actors themselves look impressive when they came out?
Oh, very much so. They had adapted the Borg walk and Borgs don�t laugh or smile or any of those things.
