Florence Pugh’s Yelena Belova in a ‘Black Widow’ sequel? Here’s where the franchise could go.

But the next special guest shows where Belova’s future potentially lies. After grieving for just a few seconds, Belova is joined by Contessa Valentina Allegra de Fontaine, played by the MCU’s most surprising acquisition to date, actress Julia Louis-Dreyfus. This was supposed to be Louis-Dreyfus’s MCU debut, but because “Black Widow” was delayed over a year because of the pandemic, she instead first appeared in “The Falcon and the Winter Soldier” on Disney Plus.
