Thunderbolts Star Geraldine Viswanathan’s Mysterious Character Seemingly Revealed

Marvel Studios might have just dropped a big hint about who Geraldine Viswanathan is playing in 2025’s Thunderbolts*. While the rest of the cast includes many actors returning to the MCU as anti-heroes, like Florence Pugh as Yelena Belova, Sebastian Stan as Bucky Barnes, and David Harbour as Red Guardian, Marvel Studios has been rather quiet on who exactly the Drive-Away Dolls and Blockers star is playing. The role, which was initially intended for Ayo Edebiri before she dropped out, has only been described as the assistant to Julia Louis-Dreyfus’ character, Valentina “Val” Allegra de Fontaine.
