HOORAH for details!
Hook's hook is on his right arm. From what I understand (and what I read in the Introduction to the play, titled "Dedication to the Five"), Hook is somewhat autobiographical to Barrie. Barrie had, at one point, lost the use of his right hand, no doubt a factor in the writing of his book.
In traditional views, also, anyone who was left handed was thought to be evil.
Hook's eyes are also blue. The symbolism of the color blue is contrary to the characteristics of the character. Blue often represents calmness, purity, understanding, and passiveness, all things that aren't any of Hook's strong points, at least on the surface. Though Barrie may have been simply creating a connection between himself - as the author - and the character, he did, perhaps unknowingly, emphasize the softer of Hook's two personalities: the saddened gentleman who fears his own mortality.
Smee is, in Barrie's play and book, a bosun. It is a common misconception that Smee is the First Mate, mainly because of the attention (as in screen time) he is given in the movies, and his seeming importance to Hook (a relationship that is, however, not emphasized whatsoever in the play or novel). Starkey is actually Hook's First Mate, but because Starkey is a rather minor character, he doesn't receive quite as much press, as it were, and so, Smee is often given the title First Mate.
Poor Starkey. I still love you! XDD
Oh gosh! Being nitpicky is my life
No worries! When I read Mr. Hart's -Capt. Hook: The Adventures of a Notorious Youth- I was jumping all over the inaccuracies of character and plot.
Hope I answered a few questions!
