Rick McCallum Q&A @ StarWars.com wrote:Q. I am not certain if this was intentional, but I noticed in the digital version Anakin's metal hand reaches and holds Padmé's hand. In the 35mm version, Anakin's metal hand is just shown hanging at his side which then cuts to them kissing. If this was an error, I would just like to know. I feel like I'm the only one around here who caught the difference.

A. Yes, you've noticed a difference between the film print version of Episode II and the version that is being shown digitally. (We call it D-cinema.)

Naturally, the process of making the thousands of physical film prints of the movie takes time, so we had to lock down that version in April. However, we had some extra time for the D-cinema distribution, so George [Lucas] had a few more days to make some final tweaks to the finished product.

At the last minute, George felt the wedding scene needed the affection of Padmé taking Anakin's mechanical hand, so just a few days before Celebration II in Indianapolis we shot it and inserted it in time for the D-cinema version.

That addition is by far the most noticeable change, but we actually made over 70 enhancements for D-cinema. Most involved sharpening, tweaking wipes and color adjustments. However, there are a handful that are definite visual effects changes. I'd be curious to hear if any fans have found any of the other changes.
