I suspect that this picturesque lighthouse has appeared in more than Message in a Bottle. According to my sources, it is one of three that show up in the film, along with Chicago Harbor Lighthouse and Pond Island, also in Maine.
I confess to not re-viewing this film lately. I couldn’t wait to see it when it came out, ten years ago, for two reasons. One, I was a huge Kevin Costner fan at the time, and two, I’d read the book by Nicholas Sparks (also available for Kindle, Sandy!). I bought the book in the airport as we were getting ready to board a vacation flight to Colorado. I read it in one day. I was disappointed in the book; the story was great, but the mechanics were poor. Not well edited, IMO. Head-hopping so often I couldn’t tell who was thinking what. Simple, but annoying habits like repeated use of the same adjectives. Sentence structure was uninspired. I mention this because it was that day that I got out my old, dusty manuscripts and decided I would one day be published. Thanks, Nick.
Aside from my then-schoolgirl-type-crush on Costner, I’ve had a life-long love affair with Paul Newman. I could watch 
him do a paper towel commercial and drop into a full swoon. Not that he ever did such a thing. He (and Costner, to some extent) was the inspiration for the character of Dane Pierce in STARCROSSED HEARTS. If you want to see Paul in one of his (IMO) sexiest early roles, see WINNING.
But I digress. Seguin Island Lighthouse is located in what is one of the foggiest places in the world, according to those wonderful Lighthouse Friends. It is Maine’s second lighthouse, and was authorized by George Washington. That’s old. The Fresnel lens is 13 feet high, and still operating, thanks to the Friends of Seguin Island, who also see to the volunteer keepers year after year.
For die-hard romantics and hanky twisters, the film is worth seeing. And you, lucky readers, got two movie recommendations for the price of one!
I though I had read somewhere that you can stay at the house at Seguin Light. Ok, that would be exciting….
