Oh, I've noticed this of late - it's fairly common practice in cities with "arthouse scenes" like NYC, but it's spread to the flyover states and megaplexes too. There were a ton of those over Christmas, but the big AMC in my area's been running movies like the 2004 Phantom of the Opera and the 2018 A Star Is Born on weekends this month, and all of these are hardly advertised (at least in venues I'm familiar with, anyway). That's not even counting Fathom Events' usually anniversary-related one-to-two night reissues. I suppose the main difference is that the Pixar movies are a lot newer, and it's not like a Fathom Events release where they're there because of popular demand. It seems so halfhearted on Disney's part.For your information, these films are only playing a few times a day. Rereleases are nothing new. NY theatres had a rerelease of Amelie recently. There are tons of others.
