Bit surprised they're dropping a trailer for this already when Black Panther isn't even out, and then you still got Infinity War to promote afterwards as well. That said, it's a nice trailer. Looks fun
I've noticed that Disney likes to drop these trailers a few weeks before their next big movie. I thought they were going to release the Infinity War trailer for Thor Ragnarok, but instead they released it after Thor but before the latest Star Wars. Then I saw the Infinity War trailer in front of Star Wars. I guess they want the internet to create a buzz for a couple weeks and then make it new again for people who don't watch trailers online.
Huh, the only Marvel trailer I got at Star Wars was Black Panther... it was the best moment of that night, too.
But seriously when it comes to trailers on the cinema itself, I thought Marvel usually kept it to only their very next movie. I thought that was a sensible approach, but apparently I'm wrong (or I'm right and they're just doing things differently in each region).
