I'm going to ingnore that

Seriously though. if it happens, I'll judge it when I see it. For my part, I was really dissapointed in seeing Excalibur ended only a couple of series in. Iirc, the guy playing the Technomage was Edward Woodwards' son, (Big Ed did make an appearance in one episode, but despite the names, I've never heard the relation officially confirmed).
Excalibur was pretty good, but like all sci-fi programs, needed a couple of series to warm up. Most execs seem to forget that, in acting, feeling comfortable depicting yourself as a cannibalistic mass-murderer is a lot lot easier than feeling comfortable thinking of yourself as an Alien etc.
Edit : This is why things like 'X-Men' films always seem to have slightly 'self concious' acting, because people aren't just playing different roles, they are interacting with entirely different environments.
