I was in Hall H every day of Comic-Con 2016, and I saw a lot of movie and TV trailers and exclusive advanced footage, including:
- Wonder Woman
- Suicide Squad
- Justice League
- Lego Batman
- King Arthur: Legend of the Sword
- Kong: Skull Island
- Fantastic Beasts and Where to Find Them
- Star Trek: Discovery
- Doctor Strange
- Thor: Ragnarok
- Spider-Man: Homecoming
- Guardians of the Galaxy Vol. 2
Most of them are available online from various sources, including officially released trailers, and surreptitiously-recorded captures of exclusive content, which I do not condone, nor do I recommend you watch. Suffice to say, it was cool.
The best looking stuff we saw was from Wonder Woman:
and Guardians of the Galaxy Vol. 2, which is officially unavailable at the time of writing. A big surprise came at the end, with the revelation that Kurt Russell’s character Ego is Peter Quill’s father, along with a the (brief) appearance of Sylvester Stallone in an as-yet unnamed role.
Other notable peaks were the Fantastic Beasts trailer:
and advanced footage and trailer for Doctor Strange.
Some of the coolest scenes were from Spider-Man: Homecoming, which was a short 10 days into shooting, but offered a surprising amount of footage, and revealed that in this version of Spider-Man, Peter Parker is very much a high school kid, and also— briefly— revealed the villain to be (unsurprisingly) the Vulture.
One of the biggest surprises of the weekend was Kong: Skull Island:
which looks absolutely phenomenal, like some awesome cross between Platoon and Jurassic Park. And that cast…
Additionally, we saw a trailer for the marvelously fun-looking King Arthur: Legend of the Sword, which puts Guy Ritchie’s personal spin in the traditional legend.
All together, I’d say it was an eventful Con.
