hm, it would get more tension, if we see Fett checking the status on the carbonite, like Lando did before, then the viewer could hope our heroes are just in time to rescue Han ...

but only showing the block, well it isn't that meaningful, not sure how it was scripted, so maybe there is something one editor likes to try (see above)

Check my link again... I have re-done the whole sequence...

Now I think I agree with you... But I did not have the resources to add it... But what about Boba fett pushing a button to close the cargo bay? A close up on his Glove or something?

The other thing is, it was really nagging me so I had to check the music cues... And I can't make up my mind if the special edition is 100% correct I think it may be lagging slightly behind where it should be....

Anyway enjoy the re-done version on the original link it sells the idea a lot better and C3-PO no longer screams "look out! behind you" as I think this is something else that was ruining the scene quite badly. I have had a go at trying to make it more emotive but it needs a lot more work and I won't do another one it's a much better effort though.
