I remember where i have seen something similar but not so similar
Remember the Prophecy AKA God’s Army, AKA God’s Secret Army
In that one, there is a very close theme, Gabriel was god’s best servant there too, from the opening where an angel (Simon) stands over another angel’s skeleton and the narrator says that war has broke in heaven, angelic host is divided, just like the days of Lucifer.
There is not much similarity in the idea of the Apocalypse, but there is allot of similarity in the idea, both about the troubles sky, both horror movies, both action movies, and both have to do with rebellious angels, but that is not all there is in similarity between the movies !
To be continued
