By January, 2010, shoreline erosion had left the Serendipity house completely in the surf. New owners hired one of the companies that moved the Cape Hatteras lighthouse to move Serendipity to a somewhat less spectacular but somewhat safer nearby lot in Rodanthe. Only the house's exterior appears in the film - the interiors existed only in a studio. The owners reportedly plan to remodel the house, recreating the studio interiors, to enhance its value as a vacation rental.
As of 2013 the house has been renamed "The Inn at Rodanthe" and completely refurbished to more closely resemble the interior movie scenes which were filmed elsewhere in North Carolina. Sun Realty manages the property and has extensive photographs of the interior, particularly the blue bedroom Richard Gere's character stays in while visiting. The unique shutter doors into the kitchen have also been recreated as have the various shutters, porches, and exterior details.
The original house was built too close to the beach, with an insufficient foundation. After the film crew left, the house was declared a public nuisance and condemned. Later, it was purchased, moved to a new location, and renovated to more closely match the house featured in the film. (The new owners were big fans.)
According to Nicholas Sparks (who wrote the book this movie was based on), the two lead characters were, in part, created after real-life happenings about the way he and his wife Cathy met and started their relationship in a small coastal town.
Three of this movies actors and actresses have appeared in the long running NBC drama Law and Order: Special Victims Unit. Christopher Meloni as Dectective Elliot Stabler, Pablo Schreiber as William Lewis and Mae Whitman as Cassidy Cornell.
