Wonder if this will be the bastardized version of Sparrow from films 2-4 or the original Sparrow. One reviewer put it this way and it's the most accurate description of the series I can muster, "The original Sparrow had the appearance of a buffoon hiding a great pirate, whereas the later Sparrow was portrayed as a great pirate, secretly hiding a buffoon."
In case you're wondering what the hell I mean, check out the look on Sparrow's face when he pulls the trigger on Barbosa in CotBP. Intense, dark, devious, and intelligent.
