In the start of Pirates of the Caribbean: The Curse of the Black Pearl, both characters have this supposed age. Here are pictures of Comodore Norrington and Weatherby Swann in the opening scene and the rest of the movie respectively:
The only change appreciable is the gray color in their hairs, but Elizabeth Swann and Will Turner are very young compared with the other two.. There have passed over 15-20 years. If Elizabeth Swann would have been 8-12 years, the Comodore would have been 20-35 years...
Comodoro: 20-33 years + 15+20 years (the time that could have passed) = 35-53 years
Elizabeth: 8-12 + 15+20 = 23-32 years
Weatherby Swann: 40-49 + 15+20 = 55-69 years.
Actual Years of Jonathan Pryce (Weatherby Swann): 69 years.
Actual Years of Jack Davenport (Comodore): 44 years.
I supposed that the time that could have passed are 20 years but the Comodore doesn't comply this because he is younger than 35 years in the film.
Why are Comodore James Norrington and Weatherby Swann the same just as young, but Elizabeth Swann and Will Turner change their age respectively?
