This has some striking imagery as I recall, I think it starts out in Black and White taking place in the middle or dark ages. It's about a group of monks who, to escape imminent death (by plague? and maybe they go for other reasons?) by tunneling through the center of the earth. They look back the way they came and see the silhouette of the angel of death fly by blowing it's trumpet. When they get to the other side they are in the far future (or the present to us (or the past because it's probably clearly the 80s or early 90s)). Because of all the pretty lights (and the film in colour) they assume they must be in Heaven, and one of them cuts himself on a broken beer bottle.
That's mainly all I remember, but there something that brings them to a forge and I think someone falls off of a church.
That's all I got.
