That’s exactly the sort of gap that makes me feel both sick and exhilarated. I’m not going to pretend it’s impossible, but the odds are slim if no one has ever bothered to catalogue the negatives. My spreadsheet shows that the 1930s archives are mostly silent about any surviving footage from that expedition. If you want to turn it into a restoration, you’ll need to track down the original studio vaults and contact the institutions that hold their 1930s reels. Even if you find a fragment, turning those black‑and‑white moments into color isn’t trivial—it’s a whole other moral duty to keep the original aesthetic intact. Still, keep looking; a lost reel can change the whole narrative, and a proper remaster would give that deep‑sea dive the dignity it deserves.
