I don’t see where such an ability could have easily be built in to the movie.
Really? A small scene in the beginning, he’s sketching something and his mother tells him to stop, that it wouldn’t amount to anything...15 seconds. But, like I said, it would have made more sense if his great-uncles’ stories had inspired him to write adventure novels based on their adventures, but alas.... otherwise, I love 80% of this film.
