I've found no definitive (which TFN is about as definitive as what I left in the toilet a few minutes ago.
That site's a cesspool... No offense intended, just a rant) answers on Antilles.
I can say that the man in ANH and the man in ROTS are about the same age. They also neither one have any resemblance CLOSE to the other (hair color different, and I believe eye color is as well from what i can gather). This is what makes me disbelieve ANY source that claims they're the same guy, lfl sanctioned or not.
ROTS guy's kid is captain in ANH? I can buy that right now... Weird, but Ic an buy it.
The guy Bulloch plays is being labeled as Captain Colton too I've noticed.
The whole thing's just a Lucasfilm fubar I think. I'm to the point I'm sticking with the guy in ANH being Colton Antilles, and I'm gonna just say "son of the guy from ROTS". Maybe named after the ship's pilot.
Which that's also a bit of a discrepency... The ship has TWO captains? Colton, and ANtilles? Makes me think Colton's maybe the legit captain and Antilles is more a security captain like Panaka would be to Padme, but that's a WHOLE other debate.
This is as bad as the Tantive IV in ROTS not matching the Tantive IV in ANH in some major ways beyond "colors" or lights beind different. Entire physical shape of the ship, beyond just some armor plating, are omitted on the ROTS ship because the ILM animators half-assed their research.
