Marvel's two-part Avengers event is everywhere again. The first full trailer for Avengers: Doomsday pulled a huge 503 million views in its first 24 hours. That made it the second-biggest trailer launch of all time behind Spider-Man: Brand New Day, as well as Disney's most-viewed trailer ever. With the trailer arriving only days before Marvel's Comic-Con Hall H presentation, where the film is expected to have a major presence, Kevin Feige has been doing more press in a single week than he sometimes does in a year.
