Yeah, I read some box office boards, and people who know what they are talking about said the Endgame Saturday is pretty much the max a movie can possibly do in a day with the current screen/seat counts in the country. Also, like others said, around Christmas you are going to have at least one big family movie and probably a few other decent movies. A 90 minute family movie has the potential to do double the endgame numbers per screen due to twice as many showings per 3 hour block. These movies are scheduled months out, so it's not like the studios would know the monster that Endgame would become and schedule around it. So yeah, it would not do $350 opening weekend at Christmas.
