As a side note too: a documentary/movie about finnish cave divers who went back to cave in Norway to retrieve bodies of their deceased buddies.

Let's hope it turns out better than the movie that was made of the Chilean miner rescue ("The 33")! Following the very successful award winning book it had an all-star cast... and it sucked. It had all the drama of watching paint dry.
