As far as how these preview screenings stack up to previous Steven Spielberg releases is tougher to say.
In the decade since then Steven Spielberg has mostly done smaller, more prestige fare that doesn’t necessitate preview screenings and blockbuster buzz.
As far as comparable preview screenings over the same period, 2013’s G.I. Joe: Retaliation earned $2.6 million in its Wednesday previews going on to pull in $51 million over its four-day Easter run.
Ready Player One has been tracking to make between $45 million and $55 million over its opening four-day weekend and should easily claim the top spot that Pacific Rim Uprising usurped from Black Panther last weekend.
