You mean like:
Tarkin: “You may fire when ready.” CHECK
Darth Vader choking an Imperial Officer together with a sarcastic verdict. CHECKBut Darth Vader does not utter any lines from the previous films in that scene as far as I can tell.
I think that was in response to “Things from the old films being shown for a second or so for no other reason then to remind us that the movie takes place in the same universe as the OT and to get the ‘‘hey I remember that’’ reaction from the audience.Check”
I’m not sure what you’re referring to when you say TFA reuses dialogue from the OT.
