^I don’t know exactly which speeder scene in Rebels you’re talking about, but I’ve always figured that landspeeders were capable of flying at altitude for short bursts because of that moment in the ROTJ speeder bike chase where Leia swoops in from above and behind the scout trooper. If the landspeeders in the scene you’re referencing are engaged in sustained flight, though, then I agree, that seems wrong.

Anton Lesser would play a great Tarkin, and I’d have liked to see him in Rogue One instead of fake Peter Cushing. He’s significantly shorter than Cushing, but they could have gotten around that with staging.
