Anybody know this movie?

This movie was about a woman who will give birth to gods(or devils) son to prevent(or start) apocalypse, she was impregnated by two different men in the same day, it has to be a mixture of two men. As far as I remember one was in the beach, one of the men's name was otto or olaf, there was a big sacred book hidden in a stone grave in a church or sthg. The devil(or god) was trying to stop the kid and anyone trying was killed etc. even one guys house was hit by a meteorite. Most probably it took place in england.

Any ideas?
