The list of celebrity attendees for the world premiere of "Avengers: Age of Ultron" has surfaced. What would normally be an uninteresting document has drawn a lot of attention though as the section for the film's cast includes two fairly well known actresses who have not been mentioned as part of the cast before. Specifically, both Julie Delpy ("Before Sunrise") and Linda Cardellini ("Scooby-Doo") have been slotted in amongst the other cast members of the film including Chris Hemsworth and Chris Evans.
