Walter was asked about his experience on Babylon 5 and he said it was a great experience and his dream come true. While he enjoyed his time on Star Trek and the experience shaped his life for 40 years and made it possible for him to do other things, Babylon 5 made him feel like an actor, like he was truly contributing something to a character that had depth, conflict and was dimensional. Each time he was asked to perform on that show, it was a thrill. Unfortunately, the spinoff, Crusade, was canceled two episodes before his role aired, but it was a very exciting one where he was an outlaw in space who was on the run and the episode he would have been in involved him making a deal with the powers that be to trade information for the return of his shuttle. In one of the last scenes, he gets in his shuttle and flies off into space and as he is flying off, a humungous spaceship looms, the mother ship, which opened up all sorts of wonderful possibilities. He said it was a sad day when the show was canceled. He was asked whether he thought Babylon 5 and his character, Bester, would have the longevity they did when he first started on the show and he said he didn't really have much of a feeling about it at the time. He was originally slated to play a different character, but that didn't work out because of time conflicts and then he had the opportunity to play Bester, which obviously worked out well. By the time they got into the second season, he started to realize that the character had some life.
He was then asked about a show he was in called The Starlost which didn't survive and he was asked what he thought about why it failed, despite the top names that played in it. He told the fan that he wanted to commiserate with him on the poverty of experience he must have had as a child if this particular show resulted in wonderful childhood memories for him, because they obviously didn't remember the show the same way, to which the audience erupted in laughter. Walter didn't recall it as state of the art technology, but more like a daytime soap opera since they mostly used soap opera directors. He liked what he did in Starlost, he just didn't feel it was a very well done show.
When asked about the shows and movies he has done and which ones he likes to watch the most and which were the most fun to do, Walter responded that he doesn't really like to watch himself that much anymore. He looks at himself and wonders who that baby is, with his whole life ahead of him. He tries not to dwell in the past, but prefers to focus on what he can do today, what challenges can he fulfill today. Philosophically, that's the way to go. He believes you stay younger thinking of the future rather than focusing on the "good ole days."
