10 Awesome Actors Totally Wasted By The MCU
2. Julie Delpy - Avengers: Age Of Ultron
Surely nobody could've ever expected to see the brilliant Julie Delpy show up in the MCU, and considering how utterly piecemeal her role was in Avengers: Age of Ultron, you'd be forgiven for forgetting she was ever in it at all.
Delpy, best known for her sublime work as both co-writer and actress in Richard Linklater's Before trilogy, appears briefly in a flashback in the Avengers sequel as Madame B, Black Widow's (Scarlett Johansson) stern trainer in the Red Room program.
It's a nothing role which could've been filled by basically any actress, and certainly didn't require the talents of a two-time Oscar nominee.
Fingers are crossed that Delpy might show up for a more substantial secret cameo in the upcoming Black Widow movie, but that's not terribly likely.
