There is also a TV adaptation from 1999), where the chronology is a bit mixed-up because it presents the destruction of Sodom and Gomorrah as some sort of "prelude" to the Flood, whereas in the Bible the Sodom story is several hundred years after Noah. The reason why I'm bringing this up is that in that film, the destruction of Sodom is presented with fireballs/meteorites, which also feature in this linked trailer, so I'm lead to think this film will also distill the two stories together in some way (there is no fire-related destruction in the Bible anywhere near the Flood story).
Also, I'm wondering if they will be incorporating popular/deuterocanonical traditions a la The Passion of the Christ - for example, Methuselah dying seven days before the Flood.
Hopkins probably plays Methuselah. And I had always thought the Sodom story was antediluvian... How many times must the LORD cleans the world He so incompetently made? Clearly He has very sucky people-modeling skills.
