Bryan Fuller's reboot of the campy TV series The Munsters (retitled in the reboot to Mockingbird Lane) could have been much more serious. Like Eddie Munster kills a bunch of people serious.
This rejected concept art from artist John Gallagher shows a whole new direction for Mockingbird Lane. Herman looks like an actual monster made from dead human parts, grandpa is much creepier and Eddie is a full-blown monster. Obviously Fuller went another direction, but you can still see glimmers from this work in the eventual pilot. Specifically in the house exterior.
