The party was fun. No one really checked out ticket or badge, only ID. Depending on your bartender, you could end up with a really strong mule too. They gave out sunglasses and cassettes which was cool and had a couple photo op spots.
They rented out the whole theater so every screen was showing it. However, I believe the party groups were ushered into two of the 8 theaters; theater 3 got sunglasses & wigs (for the social media promo shot) and Charlize & director and theater i think 5 or 6 was given Charlize & director. If you didn't go to the party and just the movie I don't think they gave you anything but a movie.
We got lucky and were an early group into the movie. We accidentally sat in one of the reserved rows (no one said we couldn't and someone before us had already pulled down the tape) and by the time they realized what happened, the only spot with enough chairs together for us was in one of the front rows. Turned out to be great since it was near Charlize when she sat for the promo shot.
