Part 5 Version 2 was just edited a little differently. It's said to have deleted scenes but I watched the original and version 2 scene by scene and didn't notice anything different accept a few scenes edited around differently. Perhaps someone with a better eye could catch the differences. It's suppose to be 10 mins longer with extra gore??

Part 6 tv had alternate "clean" dialogue, a different killing of the cop (part of the deleted scene in the boxed set) and a scene where the cops are trying to escape the prison cell.

JGTH has TONS of extra footage not in the theatrical or director's cut!
