Black Widow: 10 Major New Details Revealed About The Marvel Movie

10. The Movie Will Finally Reveal What Happened In Budapest

Black Widow and Hawkeye's shared history in Budapest was first referenced in 2012's The Avengers, when it was revealed that they met for the first time in Hungary's capital city when Clint Barton recruited Nastasha Romanoff to S.H.I.E.L.D. (rather than taking her out).

Now, Scarlett Johansson has confirmed that the upcoming Black Widow movie will finally shed some light on that. "We all agreed that we had to find out what happened in Budapest," she acknowledged. "That started out as this throwaway line which Joss Whedon threw into Marvel's The Avengers as a funny moment between Hawkeye and Black Widow."

"We thought that if we don’t go back to Budapest and find out what really happened there, people will feel unsatisfied. I wondered what did happen there? Black Widow is not about what happened in Budapest, but it's a huge jumping-off point for us to understand the heaviness of Natasha’s burden."

It sounds like fans can look forward to a flashback at the very least, which likely confirms rumours that Jeremy Renner will be reprising the role of Hawkeye. How it factors into the plot remains to be seen, but this book indicates that Natasha will actually be returning to Budapest in the present day...
