> Other films that have not yet screened because of filmmaker stipulations include 100 Years starring John Malkovich. The short film is from 2015 but has been placed in time-locked safes that won’t open until 2115, 100 years after the film was made. I wonder how one goes about engineering a "time-locked safe" such that it opens, reliably, only after 100 years...

You could power a clock with a radioactive isotope and it could get you 100 years worth of power. With a big enough spring you could also theoretically get a small mechanical watch-like clockwork to last that long, however calibrating it to be accurate and not wear too much over such a long time span would be difficult.

  Or just power or wind the clock externally. If it's [electro]mechanical, losing power or forgetting to wind it will only extend the period of time for which it remains closed. Otherwise it would need an internal backup battery, which, if it's only powering an extremely low power clock and nothing mechanical, could last that long with the right chemistry. Solar cells could also last a hundred years, suitably encased, with some reduction in effectiveness due to ionization.

The most reliable way is to set up a trust & hire a big bank to hold it for 100 years in a deposit box.

I'm reminded of those long gear reductions where the last gear is calculated to turn once every century or so. You'd need a lot of power to make that work here, at least the naive version of it.

https://en.m.wikipedia.org/wiki/100_Years_(film) https://en.m.wikipedia.org/wiki/100_Years_(film) It's just an ad. I'd be willing to bet that there is nothing in the safe and the film is just a file in some corporate cloud that will be deleted in 10 years when everyone involved in the marketing stunt has moved on to other jobs.
