Happy Back To The Future Day!
Here is a before and after shot from BTTF 2, where Marty is ‘attacked’ by the holographic Jaws billboard.
This part of Courthouse Square at Universal Studios has changed significantly over the years. It even burnt down in 2008 and was completely rebuilt. BTTF built the set specifically for the movie, but the rest of the area is quite different too. Only the turret on the building is similar, as well as some of the buildings down the road on the right.
