Yeah, but actors appearing in both series in different roles isn't really relevant to whether they can be in the same continuity - unless you're going to follow it through and say that Avon was once a UNIT captain who got killed before ending up as the Borad's Maylin, and Vila lived on Pluto for a while, where he called himself Goudry (and Blake's partner in their first rebellion also commanded Snowcap Base during the 1986 Cyberman invasion).
Noty to mention actors within the same series; I mean that Soolin does look suspiciously like a mutoid![]()
The actress who played Servalan played Chessene in "The Two Doctors." And didn't the guy who played Travis II also appear in "The Robots of Death"? I've only seen a bit of that story, so I'm not sure.
If the B7 and DW universes are the same, I think we have to come up with an explanation for where all of DW's alien civilizations disappeared to in B7.
I don't think anyone has mentioned Michael Keating (Vila) who was in 'The Sunmakers;' and was considered for the role of the The Doctor before the producers settled on Sylvester McCoy.
