Shackleton's ill-fated Trans-Antarctic expedition of 1914 is an amazing story of perseverance and resourcefulness. If you haven't read up on it, I highly recommend Alfred Lansing's Endurance, or Shackleton's own South (which is in the public domain, and can be found as an eBook for free, even on Amazon).
Why there hasn't been a major motion picture about it, I'll never know.
