10 Movie Facts You Probably Don’t Know

And finally, Tony Scott's deliriously entertaining naval thriller Crimson Tide unsurprisingly failed to secure the support of the U.S. Navy during its production, as they disapproved of numerous aspects of the script - namely that it centers around a mutiny onboard an American nuclear missile submarine.

As such, Crimson Tide didn't benefit from the U.S. Navy's infrastructural and technical assistance for maximum authenticity, with Scott instead working with the French Navy.

Though they provided an aircraft carrier for shooting, when it came to getting footage of a submarine submerging, the crew had to get hilariously crafty.

Ultimately the filmmakers camped out around Pearl Harbour's submarine base until a sub went out to sea, and when one left port, they followed it in a boat and helicopter, rolling cameras to try and capture the moment that the sub went underwater.

That they did, and to make it even better, the sub in question actually turned out to be the real USS Alabama. 

While Scott and his team technically did nothing illegal, it's still highly unorthodox for a film production to "steal" such an elaborate shot without the consent of those they're filming - especially when they're a powerful government entity.
