This isn’t an April Fool’s joke, this is simply Hollywood running out of ideas.
You didn’t misread the title, an actual crossover movie involving the two comedic Sony properties is in the works…and frankly it sounds like the worst idea since Abraham Lincoln said to his wife “Let’s go catch a show!”

This will be the fourth ‘Men In Black’ movie, and the third ‘Jump Street‘ installment.
So without further ado, do you know what they’re planning to call it?
Drumroll please…
You guessed it:
MIB23
You may now facepalm at your own discretion.

James Bobin is reportedly attached to direct MIB 23, though there’s no release date or official cast..meaning in all probable likelihood not a single star from the other two franchises return…unless the money is right, and I mean private jet big.
It appears Hollywood is destined to expand its industry vernacular for contrived things, in future years it will undoubtedly be interchangeable to say “jumping the shark”, “nuking the fridge”, or “you just went full MIB23”.
