It really is a wish list and just some people having a good time thinking who would make good or at least decent portrayals of some characters. I agree it will more than likely be a sight based show, much like Andromeda.
Most of the episodes will take place in some city that they can use over and over again and when they go out outside of it they can just use some forest.
They may have one semi famous person on the show ala Kevin Sorbo, but most of the others should be unknowns. If they have well known characters show up then maybe they should use bigger named actors. Andromeda has kind of used this with important characters they bring in.
I keep using the Andromeda reference due to the fact it is made by the same company. I would not expect the series too show up until at least 2003 if they are still working on scripts and there is no list of actors yet.
I think Fabio would not be a good Wulfgar, he has a heavy Swedish accent and is just goofy.
Alan Rickman could be cool, just not sure who yet. Stan Lee as a narrator would be cool, reminds me of the old Spider Man and his Amazing Friends.
