The most I've ever seen in one movie is Twister. The truck they were in demolished one minute, new the next. One minute, broken windshield, the
next not.
My favorite is the movie "War and Rememberances". It's the scene where the SBD's are flying off to attack the Japanese fleet during the Battle of
Midway. The director just has show a "fly by" with the carrier in the background. It has an angled flight deck - Wrong!!!! Angled flight decks
weren't developed until after the Korean War.
The one I always laugh at is in Star Wars.A group of stormtrooper are running through a wide door which is closing from above on the deathstar.One
hapless stormtrooper runs straight into the descending door so hard he falls backwards before picking himself up and carrying on as if nothing had
happenned.
