That's like asking who is Christopher Syn?
The books are great, there are several prequels (didn't we used to call prequels "origin stories").
There are two other movies, Peter Cushing in a 1962 Hammer film released as Night Creatures here but was originally Captain Clegg which was basically a remake of 1937 Dr. Syn.
Disney has the best theme song... but
"Oh, here’s to the feet that have walked the plank,
Yo ho! for the dead man’s throttle,
And here’s to the corpses floating round in the tank,
And the dead man’s teeth in the bottle."
