The red carpet for the new Haunted Mansion movie was populated by Disneyland costumed characters during the SAG-AFTRA strike. The strike, which began on July 14, prevents actors from attending promotional events for struck productions. This may result in delayed release dates on some upcoming projects, but Haunted Mansion (which is inspired by the Disneyland theme park attraction of the same name) was already set for release on July 28, so the promotional campaign has been in full swing up to this point.
