This week, check out one of the most critically acclaimed international films of 2025, as Iranian director Jafar Panahi's It Was Just an Accident comes to digital. Winner of the Palme d'Or at this year's Cannes Film Festival, and nominated for four Golden Globes and two Oscars, it's a major awards season contender for good reason. This tale of former political prisoners trying to get revenge on the man they believe to be their former torturer is equal parts darkly funny and a scathing critique of authoritarianism.

The algorithm maintains a running "best distance" that starts at infinity. As it walks the tree, it checks each visited point and updates the best distance if it finds something closer. Before recursing into a child node, it checks whether the closest possible point in that child's bounding box is farther than the current best. If so, the entire subtree gets pruned.
