So we are down to only two mystery movies today.
Resolved:
5, 8, and 10 were taken out of play by Wayne, the OP, just offering up the answers after none of us could solve them.
Still in Play:
11. Submitted by Thanks for the Crepes: This one features donuts in an armored car in an already flooded town that is downstream from an old dam that's questionable under the circumstances, and eventually bursts during the movie, further flooding the town.
12. Submitted by liuzhou:
"chicken sandwiches and cornets of caviar"
No Googling!
