Glacier calving - largest caught on film

This is an HD video - look at 1:50, it appears that an old warship on it's side is coming out of the glacier.  I know it's just an illusion a trick of the ice and the light, but it looks real for a few seconds.

But this a new Documentary in theaters their website is:
