Four wide releases with no entry above $30 million make for a potentially strong late September box office weekend, with Avengers: Endgame: Encore, A24's Primetime, Paramount's Brad Pitt dog film Heart of the Beast and DreamWorks Animation's Forgotten Island targeting different audiences. Analysts see a real chance of the best late September frame since 2018, when the four films combined for $106.4 million across the weekend.
