Avengers: Endgame - 6 Big Ways The Trailer Could Be Lying To You
1. The Entire Trailer Could Consist Of Shots Not In The Movie
This might seem like a bit of a stretch, but it's entirely possible that literally everything the trailer showed us was a lie, and none of the footage will appear in the full movie.
Marvel isn't afraid to pull stunts like this, as they've demonstrated in the past. The single biggest shot from any of Infinity War's trailers - Cap, Hulk, Bucky, Rhodey and others running into battle - was nowhere to be found in the film. That shot looked quite expensive too, proving that Marvel will do whatever it takes to throw fans off and give them a surprising experience.
Interestingly, nothing in the Endgame trailer looks even half as costly to produce as the above shot does. Mostly just shots of people stood around talking, those quick glimpses of Thor, Nebula, Banner and Clint - plus the Cap/Natasha scenes - wouldn't have taken much effort to shoot, and could have been done during the reshoots, specifically for this trailer.
Most of them even look like they used the same set. That shot of Thor was filmed in the same location as the closing stinger - note the identical wall in the background (see image below). Many fans were disappointed that the trailer lacked action, but maybe that's because Marvel quickly assembled these shots in a day, for this teaser.
Granted, the shots of Tony in space would've required some visual effects work - as would the Thanos stuff - but it doesn't look super complicated, and it could even be the case that these parts are in the film, but the rest isn't.
Only time will tell if any of this speculation is accurate, but it does seem like a safe bet to assume that not every shot in the trailer will make it into the final cut.
