I kept waiting for Earth: Final Conflict to be a game time answer.
If you're looking for a truly terrible Biblical TV movie, I highly recommend the 1999 Noah's Ark movie with Jon Voight, Mary Steenburgen, Alexis Denisof, Emily Mortimer, Sydney Tamia Poitier, and F. Murray Abraham as Lot, a character who has nothing to do with the Noah story in any way in The Bible. See it just to watch him get sucked up into a water tornado and Carol Kane turn into a pillar of salt.
Oh, also James Coburn plays a goods peddler who visits the ark post-flood and sells them stuff like a rice paddy hat for a penguin.
