10 Marvel Cinematic Universe Surprises The Trailers Ruined
5. Captain America - Caps Ends Up In Modern Times
This spoilerfic reveal didn't come from a cinematic trailer, but an ad which aired on TV just weeks before Captain America: The First Avenger hit.
The fact Cap ends up in modern times to battle alongside his fellow Avengers was an inevitability to anyone with even a basic knowledge of Marvel Comics, but casual cinemagoers who didn't catch this advert will no doubt have been stunned when the World War II setting was jettisoned at the end.
The ad basically gave the movie's ending away, showing Steve Rogers in modern day America, flanked by SHIELD agents in Times Square before telling fans to look out for a first look at Avengers Assemble after the film.
