Well, actually, Seaview leans more towards the French Eclectic style, which didn't come into vogue until 1920 - not surprising since it was built in the 1920s. Though the Collinses were often way ahead of their time.
The one thing Seaview does have going for it is that French Eclectic incorporates the half-timbering of and the materials used in the Tudor style, which to my mind would make for a more appropriate Collinwood.
The interesting thing will be to see what the backstory of Collinwood will be in the film. As I've said before, I loved how the Collinwood of the '91 series was originally built in England, then disassembled, shipped stone by stone to Collinsport, and then reassembled. And with that sort of history, it wouldn't be at all odd to use a shooting location in England.
