The producers therefore used the same group of people (as many as 12) in various mid-level speaking roles, taking full head and body casts from each. The group came to be unofficially known by the production as the "Babylon 5 Alien Rep Group."<ref>{{Cite web |url=http://jmsnews.com/messages/message?id=17146 |title=JMSNews JMS: Utility Actor???? |last=Straczynski |first=J.
