Ever since 1975, when Steven Spielberg’s Jaws gobbled up every box-office record in sight, Hollywood has treated the warmer weeks of the year like a launching ground for its most expensive, extravagant productions—a whole season of would-be blockbusters, vying for our moviegoing attention from the beginning of May until the end of August. There will, of course, will be very few, if any, blockbusters coming to a theater near you this summer. On a brand new episode of Film Club, critics A.A. Dowd and Katie Rife offer a history lesson of this suddenly halted tradition, before debating which year, in the 45 since Jaws, gave us the greatest summer blockbuster season.
