Movie Marathon Events

Got nothing to do for the next 24 hours? Why not attend a 24-hour movie marathon? But where can you find the best movie marathon events in the world?

I have cataloged recurring movie marathon events below in two formats. The first is a list, with a link to a website for the event (when available). The second is this Google map. For your convenience, the map is embedded below.

There are one-off movie marathon events out there, but since I can’t know for sure if they’ll ever return, I have focused specifically on the events that have some staying power. If you know of any other recurring events that aren’t listed, comment on this page!
