Not sure Added Lucrehulk, Hammerhead and U-wing to a couple of shots during the battle. They are from YouTube’s green screen, so I’ll keep them if they are at least bearable.
In the background and slightly blurred the should look fine. Try the fan film “Battle of the Dreadnoughts” for some extra battle footage…
Not sure Added a couple of shots from deleted scenes (probably the rebels firing from the Falcon’s turrets).
Yes, because those guys are seen behind Lando and then disappear. And if I’m not mistaken one of the dudes is seen on TROS firing the turret 😉
(I’d also recommend you add some of the bunker action, to make up for the trimmed Ewok action)
