Peter Duncan's voice was dubbed by someone else, as Duncan sounded too British.

In Helena's opening narration, she states that the surrounding stars are so close that the Alphans are "constantly bathed in a lovely blue light" (undoubtedly to provide an explanation ahead of time as to how they come across so many planets within a short time period). We see no evidence of a constant blue light, which would be most prominent when Koenig and Maya are out in space.
