My husband told me about a film he saw on television when he was a child that terrified him. He was on holiday at the time in mexico, about 20 some years ago. The film was old then, not sure how old. I told him I would find it, but I've had no luck so far. If any of this rings a bell do tell!
(things in quotes are uncertain) He describes the film as being a black and white, "silent" horror short: The film is set in a mansion, a man "pushes" an elderly man "his father" down the stairs and he dies. The elderly man is buried in a crypt outside of the mansion, and the younger man inherits his wealth and his house. There is a painting "half-way up the stairs" of the mansion and the crypt outside, the painting begins to change and shows the crypt door open, then a hand reaching out. The man begins to panic as the dead man comes out of the crypt in the painting, each time he passes the painting on the stairs the dead man is closer. "As the dead man reaches the house the movie cuts and the next scene is of the younger man dead."
The haunted by a man pushed down the stairs part sounds like an episode of The Twilight Zone, except for the silent part. The aging & painting part could also be some loose adaptation of, or something inspired by "The Picture of Dorian Gray." I don't remember "Alfred Hitchcock Presents" much at all, but it could be an episode of that as well.
It sound almost exactly like THE CEMETERY from the Night Gallery pilot film starring Ozzie Davis & Roddy McDowell A couple of things;
It's not B&W, but his could be explained by faulty memory or a B&W tv. It's also possible a rural UHF station was broadcasting in B&W, especially in Mexico decades ago
It's not silent, but there's not a lot of dialog either; Again memory, bum speaker, or weird/dubbed broadcast.
It's not very old, but the sets have a southern gothic look, so again, easy mistake for a kid.
You can find it here on Vimeo, and see if it sparks any memories
I don't recognize the plot specifically but it sound like an "Old, Dark House" film, a sub-genre of sorts that was popular during the silent era, though there area a few talkie examples too. Basically its a murder mystery that's initially presented as a haunted house story but in the final act the culprit is proved to be a human one; kind of like 'Scooby-Doo'. Don't know if this helps but maybe if there's a list you could work off of somewhere...
