I just saw Rogue One and have a question about a possible reference, if it is one.
The Death Star is used twice in RO, just as in A New Hope (it is destroyed before firing the second time in ANH).
In ANH, they used the same footage for the preparation of the blast. In RO I think that I noticed that they also use the same footage (not the footage from ANH but from RO) twice.
Might this be a reference or is it just my imagination?
