Question: do they actually film movies at universal studios

Answer: Yes, The Tour is the signature attraction at the park, and goes into a working movie studio, with various film sets on the lot. In recent years, guests have sat in multi-car trams for the duration of the ride. The Tour lasts about 45--60 minutes and is led by a live tour guide who can be seen throughout the tram on video screens. It travels through the Front Lot, Backlot and various attractions, passing sets and props from movies along the way.
