Fifty years ago this summer, Jaws was released in the US. Directed by Steven Spielberg and based on the bestselling novel by Peter Benchley, the film - about a coastal resort town threatened by a great white stark at the busiest time of the year - was a groundbreaking box office phenomenon.

Jaws changed the industry overnight - pioneering new marketing and release patterns, and altering the focus and mix of movies that Hollywood made - some say for the worse.

From Jaws and Star Wars through to the double whammy of Barbenheimer, summer blockbusters have dominated cinemas. But is this changing? And is there more to the summer blockbuster than big box office and a summer release date? Ellen E Jones and Mark Kermode join the queue for popcorn to explore the genre.

Mark speaks to critic and author Tim Robey about how Jaws went from potential disaster to record-breaking hit, and about the summer blockbusters that followed. And he also speaks to Jenny He, senior exhibitions curator at the Academy Museum of Motion Pictures in Los Angeles, about the museum’s forthcoming ‘Jaws: The Exhibition’ and the marketing techniques that helped make the 1975 film such a success.

Meanwhile, Ellen talks to pop culture critic Kayleigh Donaldson about box office mega-hits for the modern age - and how the inescapable megalith of Marvel has impacted the summer film landscape.

And Ellen also speaks to Canadian filmmaker Nyla Innuksuk about her 2022 film Slash/Back - a Spielberg-influenced summer-blockbuster-in-spirit sci-fi adventure movie set in the remote Arctic fishing town of Pangnirtung.
