BTTF isn't exactly an "attraction" since nothing happens with the set/area (except the Courthouse has survived backlot fires). And KONG would need to be the defunct original..Back to the Future and Kong.....pleaseeeeeee
Considering JAWS was the first magnet. It's more likely Earthquake will get one. Psycho is possible since Norman brings the set to life (and death). The old Breaking Bridge would be a nice Studio Tour nod for the 60th.
