After their names appeared on a list of cast members attending the "Avengers: Age of Ultron" premiere, Disney confirmed to SlashFilm that Julie Delpy ("Before Sunrise") and Linda Cardellini ("Freaks and Geeks," "ER") were involved in the film.

Though Disney confirmed that the actresses' names were not a misprint on the aforementioned list, the representative did not offer any additional details, which leaves their roles unknown at this time. Their capacity within the film is likewise unknown, though their reputations and this late announcement suggest that they may only have cameo roles.

Marvel's "Avengers: Age of Ultron" arrives in theaters on May 1.
