In the movie "Indiana Jones and the Last Crusade," there’s a scene in which Indy, played, of course, by Harrison Ford and his dad, played by Sean Connery, are in a castle in Nazi Germany, tied to the same chair, trying to get loose. They scoot into a fireplace to get away from a fire which is consuming the room they’re in.

While trying to unbind his hands, Indiana Jones accidentally leans into a metal bar, which swivels the pair into a hidden room, where Nazi military personnel are working.

And while many of us may think hidden rooms and passageways are only for Hollywood — or castles — that is not necessarily the case.

Steve Humble is the president and founder of Creative Home Engineering, a Gilbert-based company that specializes in making secret passageway doors for luxury homes.

While a specific event may not lead to a desire for more security, some experts say a series of negative or violent stories can have that effect. Jeff McCall is a professor of Media Studies at DePauw University in Indiana and has written about what’s called “mean world syndrome.”
