Opening up about how her character came into shape in The Falcon And The Winter Soldier, series director Kari Skogland said this.
One of the most exciting aspects of The Falcon and the Winter Soldier was the big-time surprise cameo from Julia Louis-Dreyfus as a prominent Marvel Comics character, Contessa Valentina Allegra de la Fontaine.
Her appearance in the Disney+ original has opened up hundreds of possibilities for the future expansion of the Marvel Cinematic Universe.
Contessa Valentina indeed is a part of deeper Marvel comics storylines, which haven’t been hinted at in the last 12 years of the Marvel Cinematic Universe.
