James Cameron, maker of The Abyss, probably got the memo. But the memo read “You’re going to need to make much more successful movies before they let you do that again.”
Which a bunch of people found out as soon as they started bitching about why some random Hollywood asshole was commenting on the Oceangate disaster.
If anyone can manage underwater filming safely it's probably him.
He has also confessed that his ulterior motive for making Titanic was to get a studio to pay for an expedition to the Titanic. Which they did.

Looks like in Cameron’s case it was a double fault situation. No alarm on the primary, and the safety person didn’t check his emergency gear. That guy shouldn’t have been punched he should have been fired. And had his license suspended.
