Hence the surprise when we found out that Bex Mader was back on set, or the ability to introduce Marian in the Season 3 Finale without a lot of fanfair. The casting agents have done a very good job of casting the roles as they come, and the everyone has done a good job making sure that the roles, once cast, are filled only by the original actor (Robin Hood being the one glaring exception). Very true. And the good thing about Robin Hood is that it can easily be explained with a glamor spell (which I believe is what they are planning on doing).
