17 Moments That Will Define Upcoming MCU Movies

16. Budapest - Black Widow

It might not be 100% set in stone just yet, but it looks like we're finally getting the Black Widow stand-alone movie that should have happened years ago, with Scarlett Johnansson back as the former Soviet spy and a period setting that should explore how she came to be on the side of the good guys.

The most intriguing thing about Black Widow is that we've already had compelling hints at Natasha's backstory, with her mentioning the red in her ledger and a flash of her origin in the Red Room in Avengers: Age Of Ultron. There was also, of course, those mentions of Budapest in The Avengers, which was the site of some sort of major mission involving both Nat and Clint Barton before their Avengers days.

If the Widow origin movie doesn't end with that mission, they're mising a serious trick.
