“They snuck me onto set every day in this stunning hooded cloak,” she said, alongside a video of her in the cloak, oversized sunglasses and gloves.

She then joked, “I have worn it every day since. Obviously.”

“Your entrance was one for the ages,” agreed one fan.

According to The Wrap, Louis-Dreyfus’ character in the comic books is also known as Madam Hydra, a “bizarro-world” version of Nick Fury. She eventually leads an all-female team, Femme Force, of S.H.I.E.L.D. agents.

In “The Falcon and The Winter Soldier”, she will help transform John Walker (Wyatt Russell) into an agent and create her own team.
