I believe that using one of the iconic sites such as Collinwood in this movie will make it all the harder for some fans to fully realize this DS movie is not going to be the one they grew up watching or their folks watched as teens.
Needless to say, the consensus was that it is a big thrill to walk the grounds, as well as the halls, stairways, corridors, and even the tower room of Collinwood.
Seaview is the only star that appeared in every episode (save the first one, I believe).
