Avengers: Age Of Ultron Cast Adds Linda Cardellini & Julie Delpy

Julie Delpy ("Before Midnight") and Linda Cardellini ("New Girl") have undisclosed roles in Joss Whedon's soon to be blockbuster, Avengers: Age Of Ultron.

Earlier today, Disney released a list of cast members that will be attending the red carpet premiere of Avengers: Age Of Ultron and on that list were two surprises: Delpy and Cardellini. Disney confirmed to Slash Film that their names were "not a misprint."

French-American actress Julie Delpy is best known for starring with Ethan Hawke in Richard Linklater's Before Sunrise (1995), Before Sunset (2004), and Before Midnight (2013).

Cardellini is known for her television roles in ER, Freaks and Geeks, Mad Men and New Girl. She has also played some memorable roles in films, like Velma Dinkley in the live-action Scooby-Doo films.

Avengers: Age Of Ultron arrives in theaters May 1, 2015.
