August has literally nothing coming out (well, it does, but nothing big). That's probably what helped Guardians win the box office for so long last go around. While that wouldn't have worked this year (too close to Spider-Man and Thor 3), Disney should have scheduled Pirates 5 for August just so it has a chance to survive. This is what's coming out in May (in terms of big pictures) Guardians 2 [5th] King Arthur [12th] Snatched (Amy Schumer/Goldie Hawn comedy) [12th] Alien: Covenant [19th] Pirates 5 [26th] Baywatch [26th] Guardians should hold the top spot for at least 2 weekends, depending on the reviews of Covenant. Just my guess, but King Arthur is probably going to be the first flop of the year. Here's what June holds: Wonder Woman [2nd] Captain Underpants [2nd] (will probably do okay for movie goers with kids until Cars comes out) The Mummy [9th] Cars 3 [16th] Transformers 5 [23rd] Despicable Me 3 [30th] The House (Amy Poehler/Will Ferrell comedy) [30th] Pirates has a week, if that, to be #1 at the box office. I don't think it will flop, but it definitely won't perform as well as other movies (like Guardians, Wonder Woman, and probably Transformers).
