Well no duh, it's the same actor

In the re-released versions of the original Star Wars trilogy, they did put Hayden Christensen in the end of the movie instead of David Prowse.

There are a couple other minor changes at the end of the movie. They cycle through more cities celebrating (or alter the orignal ones) and, if you listen very closely, you can hear Jar-Jar Binks yelling "We-sa free!!"

Also, Sy Snootles, the actor in Jabba's Palace, was ANIMATED in the new version. On the Old version, she is a pupput.
