I agree that the second and third versions look very off-putting and clearly from that portion of the movie. The first one looks better in my eyes as he’s more proportionate and higher resolution, plus it’s not actually from ROTS since it’s a promo photo of him in the Tantive IV for some reason. But of course, it’s just a still photo which looks a bit odd next to the others, plus he’s in dark robes that don’t match the other three and aren’t consistent with his ghost at the end of ROTJ or behind Rey on Exegol.
Yep unfortunately it seems it would have to be video footage from some point in the saga. Maybe splice it out of the actual ROTJ scene? Or maybe there are some deleted scenes with Anakin in ROTS that might work idk.
