Definitely! It's got amazing detail, cool props, and additional content not seen in the film or only given a glimpse of. I don't know how much it is where you are but I found one on Amazon for $27 USD. My girlfriend was surprised to hear it was less than $100 USD.
It's from this book, just a poor quality photo. There might be better out there, but that's all I could find quickly.
Eh. These Harry/Credence theories are too flimsy for me.
I appreciate what you are trying to do, but I think there are too many holes in this.
Yes, in a old cut of the movie Credence got on the boat with Newt. However, that did not make the final cut, which means it is not cannon. Just like how Jacob was literally engaged before he met Queenie. Mildred did not make the final cut of the movies, she is barely cannon. The only reason she MIGHT be cannon is because information about her was published in the books related to the movies (see A Case Of Beasts )
I have a feeling that Credence is going to play a much smaller role than people think and that he will be without a body. Also if Newt was going to case a fidelus curse on Credence, he would then have to go into hiding. Meaning that chances are slim that he will be seen again.
However, as I said, I appreciate that you are working to generate new content.
The official Making of the movie books (there’s two). They’re quite nice and full of details and printed out tidbits. Plus they’re hardcover and big. I think they’d make a lovely present, if he doesn’t have them already.
