The Studio Backlot Tour reopened this morning after a 3 month refurbishment. The tram tour section now features a pre-recorded spiel despite the tour guide still being inside the tram with the guests. There are two versions of the spiel, one male and one female. No confirmation yet on whether they have a different script or if they are just used to match the onboard tour guide gender. No significant changes were made to the pre-show, Harbour Attack scene, AFI Showcase, or the actual tram tour.
