Alamo suffered outages at four theaters, two in the NYC area, plus Denver and San Francisco They blamed Sony projectors, which is curious as Sony exited the movie theater projector business in 2020: you'd think that Alamo would have phased them out and replaced them since they would have represented a severe service liability if they were to break.
At any rate, the problem seemed to be computer security/encryption certificates tied to the movies they were showing. Not all movies were affected. The distributor was scrambling to recreate certificates with longer expiration dates and - however they go about it - 'reprint' and re-issue the movies to the theaters.
The movies are shipped as encrypted files, then the certificates are needed to decrypt them. The certificate ties into the projector so the file decrypts as it is being played. DVDs and Bluray players do the same things, that's why you sometimes need to do an update to your Bluray player to play the latest titles: certificates have been updated and your old certs won't decrypt the newest stuff.
Apparently all was well on New Year's Day.
