Barring instances where these films are re-released by Disney itself as part of a wide-scale, coordinated release, Disney keeps its catalog titles in the vault.
By and large, Disney doesn’t allow many of its catalog titles to play theatrically in first-run theaters in the way other distributors do.
That’s why you don’t see animated classics like Beauty and the Beast or live-action family films like 20,000 Leagues Under the Sea and Mary Poppins playing at the local art-house or multiplex alongside new releases in the way that you do for other studios films.
