explicit OW estimate but "presales continue to grow rapidly" (though I think they're talking a little bit about a longer timeline of acceleration than last few days)
Other new releases – Send Help – performing similarly to Him, Shelter – “presales are small” and skewing much higher age 55+ than other statham films. Overindexing in the midwest.
