The tours are on a set route as to not disturb any movies shows being done at the time. There is tbbt tidbits as you tour explaining areas they filmed within Warner Brothers and there are chances you could run into a few actors while on your tour which makes it exciting. They do take you to a random studio that is being used and it gives you that feel of being on the set with the actors that film on them. For me that's well worth the visit to be that close to the actors world.
Depending on shooting schedule and lot they make ask you not to take photos
Yes you can but in case a shoot is taking place they ask you not to talk or make any noise
