I’ve mentioned this before elsewhwere…on the VHS 1995 THX fullscreen release , there is a gaffe with the lasers on the TIE Fighters being blue instead of green in ESB. It happens right after the Star Destroyers take evasive action and goes into the asteroid canyon chase . It looks more like the laser fire from the Cylon raiders in the original Battlestar Galactica for a few moments , then reverts back to the normal green fire . I wonder what the story behind that was ? Any speculation or definitive answers out there ?
Update - no screenshot, but I did confirm that this exists, after spending most of a morning digging through my closet to find my old VHS player and tapes.
Specifically, there are three affected shots just after Han says “Great. Well, we can still outmaneuver 'em” (in between which there’s the scene where several Star Destroyers nearly collide and an officer shouts “Take evasive action!”).
In the next shot where we see TIEs firing lasers (just after Han says “We’re in trouble” and leaves the cockpit), they’re green. But in the next two shots where TIEs fire lasers (as the Falcon is skimming the surface of the gigantic space-slug asteroid, just before the TIEs slam into the canyon walls), they’re blue again.
All the shots with blue lasers have either three Star Destroyers or the giant asteroid on screen; whereas the shot in between with green lasers (besides the TIEs & the Falcon) has just an empty starfield.
That’s all I noticed so far, though I haven’t checked other scenes on that VHS tape. And I don’t have any other pre-1997 VHS tapes (fullscreen or widescreen), so I don’t know how far this issue extends.
