“Strangers on a Train” is one of my favorite Alfred Hitchcock films, and I revisited it just last summer after the director’s daughter, Pat Hitchcock (who co-starred in the film), passed away at the age of 93. The movie still holds up, and though “Gone Girl” alums David Fincher and Gillian Flynn were at one point circling a modern remake, it never came together and we’ve yet to see one.

What we have seen are movies like “The Girl on the Train” starring Emily Blunt, and last year’s “The Woman in the Window” starring Amy Adams. The latter of those was another Netflix thriller that wore its Hitchcock influence (in this case, “Rear Window”) on its sleeve. It was poorly received, and since its release, we’ve also seen the spoof, “The Woman in the House Across the Street from the Girl in the Window” starring Kristen Bell.

It feels like we might be reaching a saturation point with these kinds of unofficial Hitchcock remakes, with said spoof potentially doing for them what “Walk Hard: The Dewey Cox Story” did for musical biopics (which is to say, making it a little harder to take them seriously). Hopefully, with Castro Smith behind the camera and Alba in front of it, “Confessions on the 7:45” can prove this sentiment wrong and deliver a solid psychological thriller in the vein of a Hitchcock classic.

Unger’s official website gives a more detailed synopsis of “Confessions on the 7:45,” and you can also read a sample of the book there. As yet, Netflix has not announced a release date.
