Well, whatever. My kids each have a homework pass saved up for this. My wife knows what's up, and I am planning a Thursday night showing for this one. I know people (non-nerds, mind you) who are actually taking off that Friday to go see it without kids to avoid spoilers. This movie has no ceiling. Everyone who saw any marvel movie loved at least 1 character lost in the snap. It may be the reason why Marvel put Black Panther, Spider-Man, and all but one Guardian of the Galaxy in there. They knew that, if they just snapped away Vision, Scarlet Witch, Nebula, and the (then unseen) Captain Marvel, no one would care. But, when BP grosses 700 million domestic, and then he dies in a non-sequel to his film, you can bet people will line up to see Wakanda's king return!
Also, Spider-Man. Come on.
It could debut on a Monday on the moon, and I think it would still shatter opening weekend records.
