Here's a little trip down memory lane from a family vacation to Los Angeles in 1985. The Universal Studios tour hasn't changed all that much in some areas....
Here is town square that is actually still dressed from Back To The Future! If you look carefully, the signs and the theatre were still the same...
The building's on fire!
Surprise, it's movie magic!

Jaws... this never gets old!
Ok, lies... it does...
