Just thought of one other special feature that might be added in a future edition of the ROTJ blu ray discs…
In 1983, Return Of The Jedi featured the very first THX trailer in theaters, called “Wings.”
The THX “Wings” trailer and almost all THX trailers can be downloaded in HD & 5.1 and above from here:
