Star Destroyer Bridges were grey and lighted, and should be grey and lighted, not black and dark.
They’re black n’ dark in ROTJ. I just noticed this last time I watched it. Scenes on the bridge look like the characters are hanging out after close.
Darth Vader should use both hands when handling his sabre, jokes aside.
I thought he fought one handed in the OT. He certainly does for most of the ESB fight.
