I'm trying to find the origin of a scene, possibly at the end, or at a climax of some sort, where an apocalyptic event unfolds and in a nightmarish scene, the camera points to the horizon, and rising slowly is a (probably unconvincing now) burning devil shape. I suppose the shape is like a faceless devil emoji, but with a rounded body.
In my memory of this show or film, it was probably already old when I saw it, and that was no later than the early 1990s. That's the best I have to narrow it down, sorry!
I was watching it as a kid with my dad, and I remember being vaguely disturbed by it, especially as he said something along the lines of "if you're a bad person that's what could happen!". The closest I've been able to find are photos of natural phenomena "the devils horns", except the shape is a more fuller being than just horns.
This memory is seared into my brain now, because of the comment my father made, but it might otherwise be an unremarkable show. I have no idea what this show could have been, it might even have been black and white, because I can't even remember the colours. I've attempted to search for this with google and chatbots but they fall short, so hoping that someone else will remember this.
