Up first I have "Acts of God" type flicks...
Next are the one's that I'm not sure fit the "disaster" genre or not. But they still come to my mind when I think of disaster movies.
Now, I know there are more in both categories & I am sure more that I have actually seen, but this is, I think, my mostly complete list.
When asking Rob, he started adding to my 2nd list movies such as "Lake Placid" & "Anaconda" but they don't fit for me. lol. Poor Rob, I know he must get frustrated with me. Thank God He loves me any way :)
