1. Finding indie filmmakers and giving them enormous tentpole blockbusters
"Hey! You directed a single modestly successful indie film - therefore, you'd be PERFECT for this 150 million dollar summer tentpole blockbuster franchise film!"
THAT'S the current thinking in Hollywood today, for whatever reason. Maybe it's because they figure these indie directors will be in so over their head that they'll be easy for executives to control? Maybe it's because most blockbuster shots are so effects-heavy that it'll mostly be the VFX team doing the important directing and these indie directors will just try to make the dialogue/acting pop during the 15 minutes of screentime that don't involve dinosaurs or explosions?
Either way, they'll definitely be able to channel the magic of their four-character one-location dark comedy into the 55-minute rotating battle scene.
Also should be noted that Colin Trevorrow's next film as a director is Star Wars Episode IX.
2. Releasing MAJOR MAJOR spoilers in the trailers
"You know what people hate? Genuine surprise and excitement! Let's make sure every possibly interesting plotpoint is in the marketing materials so that everyone knows about them before walking into the theater!"
Seriously - people like some air of mystery to exist before buying a ticket. After all - if you know all the important stuff, what's the point of actually SEEING the movie? Surprising stuff happening in movies is fun, and leads to positive word-of-mouth. One of the entire reasons The Sixth Sense was so successful was that people told their friends that they would NEVER see the ending coming, and people went to the theaters anticipating a surprise. You know what would have made no one wanna see The Sixth Sense? Revealing that John fucking Connor was a secret Terminator in the damn trailer. I mean, that would have ruined The Sixth Sense for a lot of other reasons too, but you know what I'm saying.
The trailer for Terminator: Genisys (ugh) and posters revealed that series mainstay John Connor was secretly a Terminator in this timeline - something not revealed until late into the film:
The INITIAL trailer for Southpaw revealed that Rachel McAdams' character - one of the above-the-title actors in the film - was killed early in the film:
The trailer The Martian - a film that won't come out for a few weeks - reveals that Matt Damon is able to contact NASA, and that his crew defies NASA's orders to go back to Mars to retrieve him. In the novel, both of these are pretty major twists that don't happen until deep into the story:
