10 Best Movies That Were Once Considered Lost, but Are Now Found (Collider)

"As unusual as it might sound, back in film's early days, the artform as a whole was sometimes treated as disposable entertainment not worth preserving. This led to the vast majority of films made before 1930 being lost, and as such, they're no longer available to be watched. It's estimated that a staggering 75% of silent films have been lost to time. The phenomenon of lost films mostly applies to the silent era, as film preservation began to improve as the decades went on, thanks to film being seen as a more worthwhile art form. However, there remained films that were released yet went missing after 1930, too, as in a pre-digital world, there still had to be physical film archived to prevent loss. Thankfully, a film being lost doesn't mean it's gone forever, as sometimes, lucky accidents have resulted in once-lost films being rediscovered." - collider.com
