The Rocketeer and Roger Rabbit are always my go-tos for replacing this. Both chronologically fit well within the Golden Age feel of Hollywood Boulevard, which I think should be maintained and improved as the entrance "land" since we're already going down the road of making everything else into transportive worlds of the movies. Roger Rabbit in particular wouldn't need that much re-theming since the queue could easily be an ACME warehouse, and updated cutout flats would honestly probably work fairly well given the subject matter.
