It's the kind of movie that could have only originated in '90s pop culture: an animated/live-action mashup featuring NBA stars, comedians, and Looney Tunes characters in a madcap comedy. Does the plot really matter? Not really — it's an icon based on its premise and characters alone. It's even celebrating its 25th anniversary in a perfect way: a sequel starring today's biggest basketball stars, set for a 2021 release.
