Blackbeard is a time traveler. He says hes brought kids to here (to neverland) from all different eras. The movie doesnt say what time he originally came from and doesnt really have any other out of place/time stuff (other than magic pirate guys kidnapping kids from ww2/ww1).
the behind the scenes explanation is all the actors and directors didnt like pirate songs but really liked that song so they used it
>we need some modern music for the young audience any ideas
>kids still like Nirvana right? let's use that
>brilliant idea John
They couldn't write original songs for people to sing?
Pointing out that anything in a peter pan movie sucks/is unrealistic/whatever like that observation is worthy of note is ungodly stupid. pic related, its you.
