The North American box office had a slow weekend, with “Dune: Part Two” missing from the lineup. “Five Nights at Freddy’s” remained in first place, followed by “Taylor Swift: The Eras Tour.” “Priscilla” expanded nationwide and “Oppenheimer” returned to IMAX screens. Despite these offerings, overall ticket sales are expected to be around $64 million, making it one of the slowest weekends of the year.
