A couple of things that didn’t seem quite right to me with Return of The Jedi 2.0 Workprint (not sure if these have been mentioned before):

REPORT-ROTJ-v2.0-WP

@ 00:36:13 - Visible film line scratch on bottom left hand side throughout shot. [Skiff leaving after Jabba’s sail barge explodes.]

@ 01:35:56 - The top, left and right sides of the screen appear to have a blue tint to most of the storm troopers this continues for some time until about 01:38:00 I think.

Okay take this second one with a grain of salt because I’m almost certainly wrong on this one.
@ 01:42:25 - The second shot (close up) of R2D2 shorting out after plugging into the power terminal to open the doors on Endor seems to have different gadgets from the original film (I could be wrong on this one and that could just be great practical effects at the time).

EDIT: Sorry, looks like FrankT caught the first one but I don’t believe anyone mentioned the second one and apparently I wasn’t crazy with the third issue as it’s indeed from the 2011 SE. Thanks for your hard work Harmy!
