So I forget where I learned this, and you guys may know this better than I do, but apparently, despite the changes being more subtle, the Empire Strikes Back Special Edition actually has the most changed scenes of the trilogy. Just a funny little thing that I wasn't expecting.

For the 1997 Special Edition

Star Wars Number of Significant Video Changes: 11.30%

The Empire Strikes Back Number of Significant Video Changes: 18.24%

Return of the Jedi Number of Significant Video Changes: 8.33%
