No, you're all wrong, I remember this! �ICEBERG� DEAD AHEAD!!!�
It�s a film called �Overboard� starring Kurt Russell and his real-life wife Goldie Finger.
He�s a struggling carpenter struggling to bring up his twelve children alone and she�s a very rich bi*ch with golden fingers and a golden horn.
After they crash into the iceberg they survive by clinging to a large piece of MDF which Kurt had been using to make a windowbox for Goldie�s porthole. Fortunately, Kurt had treated the MDF prior to the collision which meant that they reached dry land without it even beginning to warp.
Goldie then develops amnesia and Kurt manages to convince her that they are married and struggling to bring up their twelve children together. Bit by bit, they fall in love, undergoing many comedy moments along the way, but when her memory returns and she has the chance to get back with her mega-rich husband she chooses a life of struggle, struggling to bring up �her� twelve children with Kurt. Then he dies.
It�s a brilliant film with an amazing theme song by a woman with a very long face which Kurt made from MDF. Hope this helps.
