Warning: This article includes minor spoilers for the fifth episode of “The Falcon and the Winter Soldier.”

The big cameo from the latest episode of “The Falcon and the Winter Soldier” was actually meant for “Black Widow,” but due to the coronavirus pandemic, the schedule changed.

Surprise cameo in ‘The Falcon and the Winter Soldier’

Vanity Fair reports that Julia Louis-Dreyfus’ debut in the Marvel Cinematic Universe — appearing as the villain Valentina Allegra de Fontaine — was meant to take place in “Black Widow.”

  • For the uninitiated, “Black Widow” was set to debut in May 2020 before the coronavirus pandemic led to a delay. The Marvel schedule changed so that “The Falcon and the Winter Soldier” and “WandaVision” both debuted on Disney+ before ‘Black Widow’ hit movie theaters.

It’s still unclear what this means in the future for Marvel.

  • “There is no information on the size of the role or if Marvel Studios is changing this plan due to the Phase 4 release slate reshuffling. All that is known at this time is that Louis-Dreyfus was scheduled to appear in ‘Black Widow,’ and that might still be the case when the film releases in theaters and on Disney+ this July,” according to ScreenRant.

‘Black Widow’ connection

But this makes a lot of sense if you read more about Valentina Allegra de Fontaine on the Marvel fan database. She has a long, storied history as a member of SHIELD and even spent time as a member of Hydra. But she later went to prison after she was revealed to be a Russian sleeper agent while working with both SHIELD and Hydra.

We know “Black Widow” will follow Black Widow’s origin story, which takes place in Russia. So the connections between the two characters are already there.

According to Vanity Fair, this won’t be the end of Louis-Dreyfus’ time with Marvel, and she may just be the franchise’s next major villain.
