I’ve been thinking about it, and Tom Hiddleston is actually too old for a movie about a young Hook. As of this writing, Hiddleston is 41 years old, and young adult Hook would be in his 20’s, so the actor would have to be around 21-30 years old. Tom Hiddleston as a live-action Captain Hook would still be awesome to see though!
I’m very surprised no one has made a Captain Hook origin movie yet when the backstory has already been written for them by Barrie! Between the 1927 “Jas Hook at Eton” speech and the 1925 manuscript version, I think a movie, maybe even a mini-series, could be made using the material!
I’ve read summaries of of books that people have written about Hook’s backstory (I’ve never actually read the books themselves), but none of them really follow Barrie’s writings as much as they should have.
The closest to a Hook origin movie there is a young Hook in the 2015 movie Pan, and the character and movie were terribly written!
It’s possible that Disney will eventually make a Hook origin movie like they did with Maleficent and Cruella de Vil, but like those movies, most likely the Hook movie would be terrible! I’m still hoping so much that the Peter Pan live-action remake isn’t terrible!
