I've recently viewed two film adaptations whose stories may have influenced Dan Curtis and "Dark Shadows." After many years of waiting (speaking for many), the 1951 movie "I'll Never Forget You" finally came out on DVD last year as part of a Tyrone Power collection. This is the second movie based on the John Balderston play "Berkeley Square," and the movie was alternatively titled "The House in the Square" in the U.K. I haven't seen the original 1933 movie "Berkeley Square" with Leslie Howard and Heather Angel, which has never been released on VHS or DVD. I've read the play "Berkeley Square," though, and liked the 1951 version. It's a bit creaky, but I especially liked the early B&W interior scenes - the house looked too detailed and realistic to be a movie set but I haven't been able to find out for certain. The original play (itself inspired by Henry James' unfinished novel "The Sense of the Past") concerns a man obsessed with his family's history who goes back in time to the 18th century in England, where he falls in love. Some might see similarities here with the 1795 DS storyline when Victoria Winters goes back in time and meets the "original" Barnabas Collins. The ending of "I'll Never Forget You" was definitely borrowed by Dan Curtis for the ending of his excellent Hallmark production of Jack Finney's "The Love Letter." (The love interest from the past re-appears, reincarnated, in the present day.) I've written in the past how Jack Finney's original short story, "The Love Letter," inspired a sequence in DS where Julia finds a letter in a secret compartment in a desk by which Barnabas in the past is attempting to communicate with her.
Now I've just re-watched a two-part episode of "The New Twilight Zone" (1985) that I recorded on my DVR from the Chiller channel some months ago. The episode is called "A Message from Charity" and is based on a 1967 short story of the same name by a writer named William M. Lee. It's not a full-fledged time-travel story, but instead involves communication by the two young lovers across the barriers of time, similar to Jack Finney's "The Love Letter," but here involving telepathic communication rather than letters. The time periods involved are the teenaged boy in the present day and the girl living in the American colonies before the Revolutionary War. What was uncannily close to the 1795 DS storyline is that the girl, because of her advanced knowledge of the future, is accused and tried as a witch.
"A Message from Charity" was published in "The Magazine of Fantasy and Science Fiction" in November 1967. Dark Shadows' 1795 storyline began in November 1967 and ended in April 1968. What could be the explanation between the two similar themes appearing at virtually the same time? Was it already decided that Vicki would be accused of witchcraft when the DS producers decided to send her into the past? Or might that have been a later development, influenced by the story "A Message from Charity"?
"A Message from Charity" is well acted and poignant, though the production values don't quite match "The Love Letter." California stands in for Massachusetts, and in a scene where Peter is pacing in the school library, I noticed a palm tree out the window (shades of the 1991 DS Revival!).
Stories about time travel have been around since at least the 19th century. I've guessed that Henry James might have borrowed the concept from his friend H.G. Wells. Mark Twain and others had previously used the idea.
