Hard Rain

At the time of filming, the movie had the largest painted scenic backdrop ever used in a film.

Actually, firearms and ammunition will function wet, even underwater. What could keep a semi-auto from functioning eventually would be washing away of lubrication, if the water itself did not provide enough lubrication. Revolvers, pumps, bolt actions would not be affected immediately. In a matter of days, rust might keep them from functioning.

For ammunition, water would need considerable time to seep in around the primer and bullet. Many primers use a sealant after insertion to prevent this. Deactivation would be a matter of days or weeks.

The Paramount mountain is seen in much worse weather than normal; the camera pans down from the logo to scenes of flooding.
