A movie where a man travels back in time through a tunnel and kills his past self to take his place
Hello everyone!
I'm looking for a movie I watched a long time ago, but I have no idea when it was released. My memories are pretty fuzzy, so some details may be inaccurate.
Here's what I remember:
The main character is a man. He uses a narrow underground tunnel, almost like a natural burrow, located outdoors (possibly in his garden or near his house).
The tunnel is natural, very dark, and so narrow that he has to crawl through it on his stomach.
Going through the tunnel sends him a short time into the past. I don't think it's years—more likely minutes, days, weeks, or maybe a few months.
He comes out at the same location, but in the past.
He meets his past self and kills him. I think he then buries or hides the body nearby (possibly in the garden). After that, he takes his past self's place, and time continues normally.
Does this sound familiar to anyone? It's pretty vague, and I don't remember anything else because I watched it when I was a kid.
It's probably a fairly obscure movie (maybe even a TV movie), because I've searched Google and even asked ChatGPT, but neither could identify it.
Thanks in advance for any suggestions!
