Brian Carpenter

In an article in the June 2000 "special Babylon 5 double issue" of Cinefantastique Magazine (Vol 31 No 12/Vol 32 No 1), page 92, Frank Garcia wrote:
Actor Brian Carpenter who portrayed Calenn, Delenn's clan leader, was surprised when he made a startling discovery upon taking this role. "Minbaris are hard of hearing," he said. "My real ears were covered with latex, so I had to really concentrate on what other people were saying. I could hear my own voice reverberating in my head. I was thrilled that the role was large and important in the episode. I was really glad I had spent time learning my lines. I did my biggest scene in the episode, in the temple, in one take! We did go back and do a couple of pickups but basically we got it all done right away. That was very satisfying and fun; it was like doing theatre because the room was full of an 'audience' of extras, as well as the crew."
For Carpenter, filming "Atonement" provided an unexpected bonus. "I was in Child Star Heaven. Tony Dow, formerly Wally from LEAVE IT TO BEAVER, was directing the episode. He was great! He's a really nice guy and we got along well. Also, Bill Mumy, formerly Will Robinson on LOST IN SPACE and a character in at least one classic TWILIGHT ZONE, was in a couple of my scenes. He was also very friendly and fun to work with. It was a thrill to be associated with both these actors whose work I had known for years!"
