Sorry, I did not see Jason already posted videos on this in The random YouTube / Vimeo etc video thread for the Original Trilogy
No worries at all, mate - and thinking about it… this should have its own thread.
(and feel free to re-post any of those videos up in here too - if you so wish, of course. It may help younger / newer fans realise Jason Wingreen’s impactful contribution in the role of Boba, to say nothing of that distinct, chilling, and defined original voice.)
As said in amongst the other videos:-
‘Hopefully they’ll amend the documentary - or rectify the omission of Jason Wingreen in the credits… though I doubt it.’
Lucasfilm have seemingly become quite adept at re-writing the history of the Original Trilogy, and early Star Wars overall…
