I just watched the fifth Pirates of The Caribbean movie, Dead Men Tell No Tales, and noticed a potentially familiar figure during one of the flashbacks. Specifically, during a flashback to when Jack Sparrow became a Captain for the first time, the movie showed a pirate standing behind him as he surveyed his crew and his tribute:
I couldn't help but think this man in the background looks similar to, and is dressed similarly to Jack's dad, Edward Teague, from the third movie, At World's End:
Is this just a doppelganger, or is that really Jack Sparrow's father behind him in the flashback?
