In ESB, there's a scene I find very funny. Admiral Ozzel is contacted by Vader and begins to report that the fleet has jumped out of light speed and..grrrk he gets force choked. Two things about this scene:
1. If Ozzel was quick enough to cut of the vid connection with Vader, could he have survived?
2. This is the only time we see Vader perform a force choke over such a long distance. I believe he's on the same ship, just communicating via vid, but still, it's a big ship, they could be hundreds of meters from each other. Every other force choke is in close proximity.
I think it would've been awesome for Ozzel to click off the vid, recover from the choke, then hop into an escape pod. Only to get blasted out of the sky, but still...
I never took it that the video call was important. How does looking a set of pixels actually hurt the person? Vader just seemed capable of cherry picking whatever neck he wanted, and Ozzel was close enough to do it. The video feed was just dramatic effect for Piett's benefit/fear.
