Seeing how hands on Vader is in Rogue One the death of Captain Antilles looks a bit hokey. I don’t know if it could be done but if instead of just crushing his neck and throwing him against a wall it might be better if he let go of him and crushed his throat in mid air using the Force. This would make Motti seem a bit ignorant to ruffle the Sith seeing what we would then know was possible. Hopefully the arm of the Vader suit and someone dressed in the Captain’s clobber would be enough to pull off the trick.
