Look, we're not going to pretend we know everything about the LORNE documentary — details on this one are thin. But here's what we do know: there's a free screening happening at AMC Metreon, and in a city where a movie ticket now runs you north of $18 before you even think about popcorn, "free" is a word that deserves your attention.

The event is billed as a sneak preview of LORNE, a documentary that's making its way to Bay Area audiences ahead of a wider release. AMC Metreon in SoMa is hosting, which at least means you'll get the big-screen treatment in a proper theater rather than someone's projector setup in a converted garage (no shade to SF's DIY screening scene, but still).

Here's our general take on free cultural events in San Francisco: go. This city hemorrhages entertainment options that cost a small fortune — $75 comedy shows, $200 concert tickets, $15 craft beers at halftime. When something genuinely free lands on the calendar, especially at a mainstream venue like Metreon, it's worth clearing your evening.

We don't have full details on exact timing or whether seats need to be reserved in advance, so if this is on your radar, do yourself a favor and check AMC Metreon's listings or the film's social channels before you show up. Free screenings tend to fill fast, and standing in line only to get turned away is a uniquely San Francisco form of suffering.

Bottom line: free movie, decent venue, zero dollars out of your pocket. In this economy, that's about as good as it gets.
