B-Movie for Shelf Construction

Tonight I put together some more shelves in the basement. My entertainment for the night was "End of the World" starring Christopher Lee. This 1977 movie confirmed for me that there is a dark secret in the Catholic Church... the priests and nuns are really aliens! Well, a single group in this movie were. And while the group did seem to conduct a church service of sorts, the original holy people were killed by the evil aliens. Oh yeah, there is something about messages from outer space that 'predict' disasters. Confused? Here is something that passes as a summary of the plot:

A scientist discovers signals from space that appear to carry information concerning a series of seemingly unrelated natural disasters, occurring across the globe. Hoping to discover the source of these signals and who's behind them, the scientist and his wife set out on a trek to locate the intended recipient of the signals. What the couple eventually discovers is a small remote convent with occupants who are not really who they appear to be.

You can watch it yourself online. Don't say I didn't warn you... it has a bummer of an ending.
