Julia Louis-Dreyfus plays Valentina Allegra de Fontaine in the MCU — a mysterious, sharp-tongued CIA boss who’s been quietly assembling her own team. She first appeared in The Falcon and the Winter Soldier, popped up in Black Widow, and had a bigger role in Wakanda Forever. In Thunderbolts (out May 2, 2025).
Now she’s bringing together misfits like Yelena Belova, Bucky Barnes, U.S. Agent, Red Guardian, Ghost, and Taskmaster. Basically, Marvel’s anti-Avengers. And Valentina? She’s pulling the strings, but her endgame is still a mystery.
