most people don't know this, but george lucas originally planned to feature two scenes with the emperor in tesb.
due to technical difficulties with the baboon portraying emperor palpatine for that movie, the second scene was never filmed. the scene was to be similar to the scene we do see in the movie, in that it took place from vader's hyperbaric chamber aboard the executor & the emperor was to appear by hologram.
this lost scene was to appear immediately after the millennium falcon escapes the imperial blockade of bespin (cloud city). in the movie, we can see vader hurriedly leaving the bridge of the executor - this scene would have followed.
i'm happy to report that i've found a copy of the script for this lost scene from tesb, and i'm sharing it with you today. enjoy !
